Current loop output sensor transmitters for measuring the hydrostatic pressure exerted by a static head of liquid. Use these hydrostatic pressure transmitters to measure fluid level in storage tanks, processing vessels, header tanks, pump inlet head and other applications where hydrostatic pressure is used to determine liquid height.

Since 1990, Quartzdyne has designed and manufactured the industry-standard quartz pressure transducer for the downhole oil and gas industry. Our sensors are world-renowned for providing accurate, low drift, high resolution data in the most extreme conditions. Typical calibrations can result in less than ±1.0 psi in error for a 10 kpsi transducer across the calibrated temperature range.

Pressure transducers are analog devices, converting one form of energy (pressure) into an analog electrical signal. As pressure in the well increases, the electrical signal from the transducer increases, and the control panel reads the changing electrical signals. When the pumps start, the pressure in the well goes down and the electrical current decreases until the control panel calculates that the fluid has lowered to the programmed level. Pressure transducers measure this change by comparing atmospheric pressure to the pressure in the well.

Pressure transducers are supplied at a preset psi range to correspond with the depth of the water column. Specific psi ranges allow for a maximum operable depth for each pressure transducer. The sensor includes an air tube to keep an atmospheric pressure reading. This tube is typically protected by a desiccant filter, which keeps moisture and particulate matter from interfering with the devices accuracy. These filters must be replaced after they have absorbed their capacity of moisture, and they are readily available at nominal pricing for any maintenance department. Otherwise, pressure transducers have very low maintenance requirements.

Romtec Utilities can design and supply pump and lift stations with any preferred level sensing device. Pressure transducers offer a wide range of benefits that make these devices a great option for most pumping systems, but with Romtec Utilities, you can get any technology you want to make your system operate per your standards. If you have any questions about pressure transducers or any other type of level sensing device, contact Romtec Utilities to learn more or to see real pump station projects with these devices!

Companies incur thousands, if not millions, of dollars in maintenance costs to keep their pumping systems in good health. Predictive maintenance is one of the best ways to cut pump operating costs. One effective predictive maintenance technique uses an electronic differential pressure transmitter to not only monitor instantaneous pump performance, but also to identify issues related to pump health and efficiency.

All pumps perform best when they are at, or very close to, their best efficiency point (BEP) (see Figure 1). The BEP is defined by the manufacturer on its pump curve and is typically 70 to 85 percent of the shut-off head or maximum differential pressure between the suction and discharge.

Operating at the BEP is the single most important aspect for prolonging pump life and cutting maintenance time and costs. An electronic differential pressure (EdP) transmitter is well suited for monitoring the performance of a pump in applications where continuous operation is critical, such as cooling tower systems or aeration pumps in wastewater treatment.

An EdP transmitter primarily measures level and differential pressure in tanks, distillation columns or cooling towers, but it can also be used in pumping systems (see Image 1).

An EdP transmitter can monitor the suction and discharge pressure (the differential pressure) of a pump. Too high or too low suction and discharge pressures can cause various pump issues such as cavitation, loss of flow, mechanical failure, vibration issues, excessive noise, and bearing and sealing wear.

The EdP transmitter outputs values for suction, discharge and differential pressure, and other useful values. An EdP transmitter can also monitor absolute pressure at each of the two sensing points.

High and low alarms can be set for any of the monitored values. The EdP has a 4-20mA HART output for connection to an automation system, such as a programmable logic controller (PLC) or a distributed control system (DCS).

For example, cavitation occurs if the pressure falls below a liquid’s vapor pressure in the impeller or if air entrainment occurs. Monitoring the discharge pressure and comparing it to a table of correct pressures at the automation system will reveal cavitation. Monitoring pressure in the suction line can indicate problems such as leaks or a clogged valve or strainer. If suction pressure drops below preset limits, the EdP transmitter will send an alarm.

Incorrect flow rate settings are one of the typical causes of inefficient pump operation. Following is an example of how to use the EdP to set the right flow rate. For a given pump curve, first note:

The pump curve is typically provided by the manufacturer (see Figure 2). Run the pump with media flowing through the system at an arbitrary flow. Let the flow stabilize. Note the reported differential pressure. This is the total head or differential pressure of the pump.

Assuming 120 feet of water is the total head generated by this 7 horsepower (HP) pump, point A is the intersection with the 70 percent performance curve. The corresponding value on the X-axis (30 gpm) is the flow rate for the pump at an efficiency of 70 percent, corresponding to a net positive suction head (NPSHr) of 10 feet of water.

To increase efficiency and run this pump at the same total head, the flow rate needs to be increased to 55 gpm (right-most red dotted line in Figure 3) so that the intersection with the 85 percent efficiency curve will be at point B. The users should set high and low alarms on the EdP output to keep the DP tightly controlled while increasing the flow rate.

If the pump doesn’t generate 120 feet total head at the 55 gpm flow rate, this could be your first indication of an operational or mechanical issue. Check the suction pressure and ensure it is greater than NPSHr. Check the discharge pressure and calculate the HP generated and verify it matches the listed HP on the pump curve for the operating flow rate.

Assume 55 gpm is the operating flow rate for a 6 HP pump with an 8-inch impeller. The expected intersection on the performance curve for this pump would be point A (see Figure 3). The corresponding expected total head on the Y-axis would be 65 feet.

The EdP transmitter sends its outputs to an automation system that has control logic and calculations to convert the transmitter data to total head. The automation system compares the EdP transmitter outputs to the expected total head—65 feet of water in this case—and adjusts pump speed accordingly.

An EdP transmitter can pay for itself in a matter of months. Let’s use an example of a pump in a large industrial chemical company (see Figure 4). The company spends approximately $1,000 per year for seal failure and replacement because it operates its pumps below the BEP.

Point A represents the BEP of a 7-HP pump with a 10-inch impeller operating at 75 percent efficiency. If the pump is in continuous operation, the energy consumption per year would be $1,310 at 10 cents per kilowatt-hour (kWh). Point B represents the deviation from optimum, operating at only 70 percent efficiency.

The total cost of operating the pump at 70 percent efficiency is $2,151, where lost power output per year is $1,151 and repairs due to seal failure, vibration issues, other cavitation damages and associated downtime are $1,000. Total cost, considering a system of five pumps, is more than $12,000 per year.

The average cost of an EdP transmitter is $4,000. If the efficiency of the pumps is increased to 75 percent, using the techniques described in this article, annual savings amount to about $8,000 per year or $667 per month, providing a return on investment in about six months.

Over the last decade, we have seen a huge increase in the sale of constant pressure pumps. Everyone sells them and most people are buying them. Everyone wants better pressure and many of you are willing to pay more to get it. Here are my thoughts.

When the pump turns on. A conventional water system turns on the pump when the pressure drops 20 psi. A pressure switch controls the pump and usually turns the pump on at 40 psi and off at 60 psi. A constant pressure water system is controlled by a pressure sensor. The controller usually turns the pump on when the pressure drops by only 5 psi. This means that you won’t have a large fluctuation in the pressure and that is why it is called a “constant pressure system”.

The speed that the pump runs. On a conventional system, the pump runs at full speed or not at all. It is either turning 3,450 rpm or zero. A constant pressure system will vary the speed of the pump to maintain a constant pressure. You might be taking a shower and only using 4 gpm. The pump will run the entire time you are using water. But, instead of running at full speed and turning off, it will turn slowly and maintain the pressure the whole time. Its kind of like “cruise control” for your well pump.

There are built in pump protections. Most controllers do a good job of protecting the pump from dry run, voltage supply issues, waterlogged pressure tanks, etc.

Some controllers can email or text you if there is a problem. Usually these devices are additional to the constant pressure controller, but this is an option on many units.

The controllers can have problems with rural power supplies. The unit is basically a computer and it can be damaged by voltage spikes that are more common in rural areas. You should consider the power supply to your property before purchasing one of these units. If you do get one, make sure you get some sort of surge protection.

The controllers don’t like hot weather. They produce a lot of heat and they have to stay cool. So, when it is really hot outside, you might find that your controller will stop working or at least slow the pump down due to the excessive heat. Conventional systems rarely have this issue.

You don’t get the best pump protection. While the units do have built in pump protection, they are not the best at protecting your pump. A simple Pumpsaver is a great unit on a conventional system, but it won’t work on a constant pressure system. If you want great protection, stick with the original.

They are expensive. These units can range from $1,000 to $10,000 depending upon your needs. And they don’t last forever. Most units have to be completely replaced when one component goes out. If cost is an issue for you, I recommend a conventional system. In the end, they cost less to install and will cost you less over the lifetime of the well.

Do they work? Yes and no. Yes, they do a great job of keeping the pressure right in the range that you like. But, they don’t pump more water than conventional pumps. In fact, they use the exact same pump but with a different motor. So, if you have a problem with low water pressure due to high demand (like when the irrigation system is running) then switching to a constant pressure system will do nothing for you.

Is it worth it? Only you can decide that. Are you willing to pay more money and have more potential nuisance issues so that you can have very little fluctuation in pressure? A growing number of you are saying yes.
