FLOW
The Series LFM Polycarbonate Flowmeters are made of precision, injection molded
polycarbonate bodies and ttings. This series consists of LFMA, LFMB, LFMC, LFMD,
LFME and LFMF owmeters 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.
FEATURES/BENEFITS
• Low installation costs with standard in-line male NPT process connections and 90°
elbow tting for panel mount option
• Heat and chemically resistant polycarbonate body and ttings feature a low cost for
high durability
• Textured background on owmeter 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 ow reading error for LFMC, LFMD, LFME & LFMF
APPLICATIONS
• Chill water ow
• Reverse osmosis systems
• Deionized water systems
