Envco – Environmental Equipment

TX80 Turbine Insertion Flow Meters are ideal for chemical proportioning applications. For rate and total display, as well as pump pacing, the FT415 or FT420 flow indicator can be mounted directly on the TX80 Series Insertion Turbine Flowmeter. For a 4-20mA analog output only, the AO55, blind 4-20mA converter, can be mounted directly onto the meter.

The TX80 Series Turbine Insertion Flow Meters require special fittings, since they are not depth-adjustable, installation in the fitting ensures correct depth placement in the pipe. Fittings are available in PVC, brass, and stainless steel. Insertion Turbine Flowmeters are available in brass, 316 stainless steel, and polypropylene.
