Digital water flow meter, is the electronic flow meter, which display the flow rate of water. Different Industrial liquid, different pipe for 1 inch, 2 inch, use different flow meters. The different sensors include turbine, ultrasonic, orifice plate, venturi, or with shut off switch. All these flow meters, with LCD display, 4-20mA output, or other outputs. The different designs of the flowmeters have a variety of applications.

What are the types of flow sensors?
Water Flow Meters are flow meters measure and show the flow rate of water flow. Water flow measurement is important for inductrial applications, like the wastewater treatment. In principle, water flow meter types are: Electromagnetic (magnetic), Turbine, Ultrasonic, and DP. Coriolis and Oval Gear flow meters can also work for water flow measurement. These water flow meters, optional with digital display, battery, analog or pulse output. Material can be 316 stainless steel or special material.
What is the purpose of the orifice plate in this flow measuring arrangement?
Orifice plate. An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate ). Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate.
How does a turbine flow meter work?
Turbine flowmeters use the mechanical energy of the fluid to rotate a “pinwheel” (rotor) in the flow stream. Blades on the rotor are angled to transform energy from the flow stream into rotational energy. The rotor shaft spins on bearings. When the fluid moves faster, the rotor spins proportionally faster. Turbine flowmeters now constitute 7% of the world market.
Shaft rotation can be sensed mechanically or by detecting the movement of the blades. Blade movement is often detected magnetically, with each blade or embedded piece of metal generating a pulse. Turbine flowmeter sensors are typically located external to the flowing stream to avoid material of construction constraints that would result if wetted sensors were used. When the fluid moves faster, more pulses are generated. The transmitter processes the pulse signal to determine the flow of the fluid. Transmitters and sensing systems are available to sense flow in both the forward and reverse flow directions.
