Paddle Wheel Flow Meter 

This meter only indicates the flow rate. For applications requiring totalization see the meter with the totalizer feature.

This paddle wheel flow meter, when used in conjunction with the appropriate adapter, can monitor flows in pipes ranging in size from ½" to 8". Paddle wheel flow meters are universally accepted as a means of measuring flow electronically. Wide range, both in flow and temperature, negligible headloss and good accuracy at a reasonable price continue to make these meters popular. Easy removal for cleaning and repair permit these meters to be mounted in lines with moderate particulate levels.

This microprocessor based flow meter utilizes an 4 digit liquid crystal display (LCD). Sturdy, compact, and water resistant allow these meters to be mounted outdoors. Isolated monitoring locations are also viable as power is supplied by a long, eight year, life battery.

The paddle wheel, spinning at a rate linearly proportional to the velocity of the flow, activates a switch once per revolution. The time it takes the paddle to rotate, divided into the diameter of the pipe, results in the flow rate. Flow rate variations, from turbulence, are minimized by a microprocessor averaging process.

Programming is accomplished using the three embossed buttons on the face. Normal programming consists of selecting the pipe size and schedule from a list; the default units are gallons/minute and gallons. For sizes not listed, the user can calibrate the meter using the inside diameter of the pipe. Advanced programming options allow calibration in units other than gallons/minute.

Paddle wheel type meters will only operate properly when the pipe is full and the flow rate is within the recommended range. These meters will tolerate some sediment and debris however fine sand tends to bind up the paddle bearing.

Wetted Material

The paddle wheel and associated parts are injection molded from PVC plastic. The standard stainless steel paddle pin and Buna-N O-ring can be replaced with Teflon and Viton as options. An ABS enclosure houses the electronics and a scratch resistant polycarbonate faceplate with embossed buttons completes package
