KATflow 230 Portable Clamp-On Ultrasonic Flowmeter POWERFUL. PRACTICAL. PORTABLE. The KATflow 230 is easily portable but incorporates an advanced specification for situations which require comprehensive measurement features coupled with easy operation. The flowmeter has two measurement channels, which allow it to monitor two pipes simultaneously or to improve accuracy in non-ideal conditions. The KATflow 230 can also be supplied with a variety of options to meet the most diverse application requirements.

Specification • Pipe diameter range 10 mm to 6,500 mm • Temperature range for sensors -30 °C to +250 °C (-22 °F to +482 °F) • Robust IP 65 aluminium enclosure • Selectable three-line LCD display and full keypad • Battery life up to 24 hours with easily replaceable battery cartridge • Measurement of two flows simultaneously Features • Dual flow monitoring with sum , average , difference and maximum calculations • PT100 inputs for heat quantity (thermal energy) measurement • Process output options including current, open-collector, relay • Large data logger and software for sampling and data...

The Technology Behind the Measurement The KATflow non-invasive flowmeters work on the transit time ultrasonic principle. This involves sending and receiving ultrasonic pulses from a pair of sensors and examining the time difference in the signal. Katronic uses clamp-on transducers that are mounted externally on the surface of the pipe and which generate pulses that pass through the pipe wall. The flowing liquid within causes time differences in the ultrasonic signals, which are then evaluated by the flowmeter to produce an accurate flow measurement. The key principle of the method applied...
