Dwyer Instruments LFMB-04-A2 | Polycarbonate flowmeter | Range 0.1-1 GPM (.5-4 LPM) water | 1/2" male NPT | 316 SS float
Precision injection molded polycarbonate bodies and fittings make up the LFMB-04-A2 Polycarbonate Flowmeter Series. The flowmeters in this series are designated as LFMA, LFMB, LFMC, LFMD, LFME, and LFMF. Their corresponding scales are 3" (76 mm), 6" (152 mm), 5" (127 mm), 8" (203 mm), and 11" (279 mm). They have dual, straight-reading scales that can measure both LPM and GPM.

- Low installation costs thanks to the panel mount option's 90° elbow fitting and typical in-line male NPT process connections.
- The low cost, high durability polycarbonate body and fittings are resistant to heat and chemicals.
- The flowmeter bodies' textured backgrounds improve scale readability while saving time.
- Low maintenance expenses are produced by easily cleaned bodies.
- Easy visual set point indication is made possible by an adjustable set point indicator, which reduces expensive flow reading errors for LFMC, LFMD, LFME, and LFMF.
