Application Information

	Paddlewheel MW 100 Flow Meter
	Mini-Wheel Flowmeter with In-line Flow Tangential turbine flow meters continue to be the most common way to measure flow electronically in a wide range of industries. Enhancements to tangential turbine flow meter systems are producing a flow-sensing device that is smaller, easier to install, and more accurate than ever before. Malema manufactures a line of Tangential Turbine (also called Paddle Wheel) Flow meters that utilize sophisticated circuitry to foster signal conditioning.

The rotational velocity of the rotary wheel varies linearly with the average velocity of the fluid flowing through the flow meter. A square wave pulse is generated by a Hall Effect from magnets embedded in the vanes of the rotor wheel. Depending on the output version of the MW-100, the pulse signal is relayed directly, converted to a 0-5 VDC (voltage) output. The voltage model is span-adjustable over the flow range of the unit.
