Series LFM Polycarbonate Flowmeter

Brand: Dwyer Instruments, LLC

The Series LFM Polycarbonate Flowmeters are made of precision, injection molded polycarbonate bodies and fittings.

This series consists of LFMA, LFMB, LFMC, LFMD, LFME and LFMF flowmeters with 3" (76 mm), 6" (152 mm), 5" (127 mm), 6" (152 mm), 8" (203 mm) and 11" (279 mm) respective scales.

They feature dual, direct reading scales measuring in both GPM and LPM.

CAUTION: Series LFM Flowmeters are for indoor use only or areas without direct sunlight. Polycarbonate is adversely affected by ultraviolet light.
Features
  • Low installation costs with standard in-line male NPT process connections and 90° elbow fitting for panel mount option
  • Heat and chemically resistant polycarbonate body and fittings feature a low cost for high durability
  • Textured background on flowmeter bodies enhance scale readability saving time
  • Easy to clean bodies yield low maintenance costs
  • Adjustable set point indicator allows for easy visual set point indication decreasing costly flow reading error for LFMC, LFMD, LFME & LFMF
