Low cost plastic flowmeter is accurate

The electronic output from a Hall effect sensor gives NPN or PNP output pulses to drive a remote counter, offering 0.1% repeatability over a 30:1 flow range: two built-in LEDs indicate power and each output pulse. With the optional 6 point water calibration, the Titan 800 series offers 1-2% flow accuracy: the flow ranges available cover from 0.05 – 15 Litres/min. Special versions can offer a direct flow switch output, for low flow or cooling flow failure alarm, as are units suitable for high temperature operation at up to 125C.
