Dwyer Series LFM Polycarbonate Flow Meters

 Flow includes Flow Transmitters, Flow Sensors, Flow meters, Sight Flow Indicators and Water Meters. Mass Flow meters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston.

Flow meters indicate flow rate. The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or with switch output. The different designs of the flow meters have a variety of applications.

Tapered bore in-line indicators for flow rate. Ideal for high purity or corrosive liquid applications, gas and liquid applications, air samplers and medical applications. Flow meters are shipped assembled and ready for panel mounting.

The Series LFM Polycarbonate Flow Meters are made of precision, injection molded polycarbonate bodies and fittings. This series consists of LFMA, LFMB, LFMC, LFMD, LFME and LFMF flow meters 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 Flow meters 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 flow meter 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

Application

• Chill water flow
• Reverse osmosis systems
• Deionized water systems
