Excess moisture and flooding caused by broken pipes and defective appliances are detected and prevented using water sensors. Sensors, shut-off valves, and a centralized hub make up a leak detection system. The sensors are installed in areas where leaks are common, such as around faucets and beneath water heaters. This article will cover all you need to know about them and assist you in selecting the right one for your needs. Please take a peek at our Liquid Flow Regulator to discover what we have to offer.
Water flow meter types
Turbine water flow meter
The volumetric flow rate of the water is proportional to the speed of the rotating blades. Sadly, these meters can clog in dirty or chunky water, such as process water, which increases maintenance costs, so we recommend electromagnetic process flow meters for those applications. They also don't work well with low flow.

Vortex water flow meter
Vortices are the "swirls" that form as a fluid moves past an object, like river water around a rock or air currents across a wing. A sensor tab flexes from side to side in a vortex flowmeter as each vortex flows past, producing a frequency directly proportional to the volumetric flow rate. Multivariable vortex meters measure up to five process variables with one connection: volumetric flow rate, mass flow, density, pressure, and temperature. Insertion vortex meters work well on very large pipes since you can insert them by hot tapping with a Liquid Flow Regulator.
Water flow meter with ultrasonic technology
Ultrasonic water flow meters use ultrasound to measure flow. One signal is sent downstream, and the other is sent upstream by a transit-time ultrasonic meter. The meter then calculates the flow velocity by comparing the travel times of both signals. Finally, it uses this calculation to find the volumetric flow rate. The differences between the hot and cold legs can also be used to measure energy and temperature.
Clamp-on ultrasonic meters send signals through the pipe walls to measure water from outside the pipe. They are ideal for measuring Water Flow controllers in large pipes and various other processes because of this feature.
A magnetic water flow meter is a device that measures the amount of water that flows through it.
Finally, electromagnetic water flow meters measure flow using a magnetic field and Faraday's law of induction. A charge is created by liquid flowing through a magnetic field. As a result, as the fluid flows faster, it generates more voltage proportional to the water's movement. The flow meter then processes the voltage into the flow rate.
Electromagnetic water flow meters don't have great accuracy, so you can't use them for custody transfer. They can't measure ions in pure water, so they can only be called water flow meters with a qualification.
Water makes for a Water Flow Controller application because you don't need a special liner material. You can go with a simple liner like hard rubber or polyurethane for pure water, but if you anticipate corrosive chemicals or process water, you will need something else. If you are unsure what to choose, give us a call, and our experts will be happy to help.
Electromagnetic process flow meter
Electromagnetic flow meters are especially suited to measure process water flow since chunky liquids can clog turbine or vortex flow meters.
Some chemicals may attack your flow meter and shorten its lifespan. If your process water contains chemicals, you'll need a Teflon liner to prevent corrosion. Otherwise, go with polyurethane or hard rubber liners. You get more information on the Water Flow Controller.
