Liquid Flowmeters
Liquid flowmeters measure volumetric flow within a closed tube. When installed to the suction line, they serve to monitor the injection rate.

The F-30 L flowmeter is molded from polycarbonate and features a #316 stainless steel float, set point indicator, and 0.25-inch barbed & male NPT connections. Units are used for in-line installations.
F-44 Series flowmeters are available in different calibration sizes to match the suction flows of your Mazzei injector. These are molded of chemical resistant polysulfone with a #316 stainless steel float and male NPT connections. Units are available for both in-line and panel mount (90-degree elbow) installations.
