Process Atrato® Ultrasonic Pulse Flow Meters

Industrial Process Atrato® Ultrasonic Flowmeter

The Process Atrato® is based on our standard, wide ranging, Atrato® ultrasonic flow meter but packaged to address the more challenging industrial process and control environment. The body is 316 stainless steel, rated at 20 bar and the electronics are built-in and sealed to IP65. The only other wetted materials are PEEK and the customer’s choice of elastomers. The Process Atrato® is calibrated with a pre-set ‘K’ factor so all meters of the same flow range are fully interchangeable simplifying assembly and set-up procedures for OEM manufacturers. There are two adaptable frequency outputs, one PNP and NPN. Two multicolour LEDs indicate signal strength, power malfunctions and pulse outputs. Electrical connections are through a standard M12, four pin, sensor connector. Four flow ranges are available from 2 ml/min to 15 litres per minute, accuracy is ±1% over the whole flow range.
