KATflow 230

  • Katflow 230

Portable Clamp-On Ultrasonic Flowmeter

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.

Applications:

Heating, Ventilation and Air Conditioning (HVAC) measurements
Large pipe measurement with two sensor pairs in “X” configuration
Temporary replacement of conventional in-line flow meters
Building surveys on large facilities
Efficiency monitoring of heat exchangers

Specification

  • Pipe diameter range 10 mm to 6,500 mm

• Temperature range forsensors -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

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. 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 is that sound waves travelling with the flow will move faster than those travelling against it. The difference in the transit
time of these signals is proportional to the flow velocity of the liquid and consequently the flow rate.
Since elements such as flow profile, type of liquid and pipe material will have an effect on the measurement, the flowmeter compensates for and adapts to changes in the medium in order to provide reliable results. The instruments can be used in a variety of locations, from measurements on submarines to installations on systems destined for use in space, and on process fluids as different as purified water in the pharmaceutical sector and toxic chemical effluent. The flowmeters will operate on various pipe materials and diameters over a range of10 mm to 6,500 mm.
