The Varea-Com™ transmitter provides linear 4-20 mA signal proportional to flow rate. The gasketed cast-aluminum case is compact, and rated NEMA® 4, and FM approved for use in hazardous areas. The transmitter is a smart, microprocessor-based, two-wire, low-power unit. Its patented sensor with microprocessor-controlled gain is capable of filling flow correction needs at the meter, providing accurate flow information remotely to external support systems. The patented magnetic sensor with automatic gain control enables a high dynamic-capture range without sacrificing accuracy.
