Katronic KATflow 150 Ultrasonic Clamp-On Flowmeter (Fixed)

Katronic KATflow 150 Ultrasonic Clamp-On Flowmeter (Fixed)
Non-Hazardous & Hazardous Area Flowmeters
Ultrasonic Flow Meters
Katronic’s KATflow 150 is a fixed flowmeter which utilises ultrasonic technology to measure the flow rate of liquids within pipes without entering the pipe. The KATflow 150 has a practical modular design allowing for a broad range of configuration options and different transducer types to ensure the flowmeter is suitable for applications ranging from simple water flow measurement to energy flow monitoring and automated process controls.
KATflow 150 flowmeters are suitable for pipe diameters ranging from 10mm up to 6,500mm and have a lockable IP66 polycarbonate enclosure and has an LCD display and five key keypad.
Stainless steel sensors, cables and connectors are supplied as standard for temperature ranges from -30ºC to +800ºC and the KATflow 150 can be used to measure two flows simultaneously.
