Flowline EchoSafe® Explosion Proof Two-Wire Ultrasonic Level Transmitter

FM approved explosion proof for use in hazardous applications, the two-wire ultrasonic transmitter provides non-contact level measurement up to 32.8' or 10 m, and is well suited for challenging corrosive, slurry or waste liquids. Push button calibrated, the transmitter is typically selected for atmospheric bulk storage, day tank and waste sump applications located within a classified area. Media examples include sodium hypochlorite, diesel fuel and paint. The integral display and push button module enable fast and simple calibration.
