If you want to use a mechanical flow meter, they can become clogged in the event that the water is dirty or more contaminated than you anticipated. The transmitter produces an output signal from the raw transducer signal. These meters work particularly well with large pipes. The non-invasive sensor has no contact to the medium and is particularly suited for applications with strict hygienic standards. Flow sensors consist of a primary medium connection device, transducer and transmitter. According to this principle, in this sensor, a voltage difference is induced in the conductor due to the rotation of the rotor. When a fluid pushes past an obstruction, swirls are produced that develop into a vortex. De snelheid verandert met een andere stroomsnelheid. At low flow rates, it’s possible that the water velocity would be low enough for suspended solids to settle towards the bottom of the pipe, which worsens the efficiency of the pipe and will eventually lead to a buildup of contaminants that could cause damage. While some meters are designed to measure the flow of lubrication oils, polymer additives, and printing ink, others are designed to work in pharmaceuticals and wastewater treatment facilities. Today we can find various types of sensors in the market. These sensors are available in different diameters, with different flow rate ranges. While most water flow meters can be used across all applications, some meters are more effective than others for specific applications. These sensors also require a display to display the measurements. At high flow rate the laminar break up and becomes turbulent. Dismiss. Sensors play a very crucial role in today’s automatic systems. When water flows through the valve it rotates the rotor. It got its name because what is being measured is a pipe’s differential pressure. As such, a higher flow rate will invariably generate more voltage when sent through a magnetic flow meter. Pros – Compact, no moving parts, high pressure and temperature capability, can detect tiny amounts of liquids Cons – Invasive as the sensor requires contact with the liquid, requires power, certain thick substances can cause coating on the prism. The hall-effect sensor outputs the corresponding pulse signal. ... PF2D for deionized water and chemicals. Vortex flow meters are unique flow meters that measure the flow of water by using vortices.
