KATflow 150This is the premier flowmeter when you are looking for flexibility as well as performance. The practical, modular design and the wide variety of different in- and outputs allows us to compose this instrument entirely according to your requirements. The KATflow 150 is suitable for simple water flow measurements, as well as energy flow monitoring and automated process control.

The KATflow 150 (by Katronic™) is an advanced ultrasonic flowmeter for permanent installation. The dual-channel design allows you either to save cost and time by performing two independent measurements simultaneously. Or you can install two pairs of transducers on a single pipe especially for locations with non-ideal flow conditions. Where this is applied the sum, difference, average and maximum calculations are available in order to provide further processing of the data.

For ATEX-zones we recommend the KATflow 170 in addition to this KATflow 150.


The KATflow 150 has an IP66 housing with a digital display that is protected by an easy-to-open cover. The innovative display shows the information about your flow measurement and the scope of the measurement signal.

1 or 2 channel(s)

The KATflow 150 of U-F-M can be supplied with one or two measurement channels.
With the dual-channel model, you have the option of measuring two pipes simultaneously by means of two pairs of sensors.
In addition, you can perform a multi-path configuration measurement.

Measurement capabilities

The KATflow 150 offers a heat quantity measurement function that turns the instrument into a thermal energy meter, using two clamp-on PT100 sensors.

Also suitable for :
– Non-invasive Energy measurements, for example: HVAC systems (Heating, Ventilation and AirConditioning)
– PressureTemperature and Viscosity compensated flow measuring
– Concentration measurements like product recognition (possible by adding optional function that transmits the speed of sound through a current output).

  • Due to the variety of input / outputs and serial communication options, the KATflow 150 can easily be used for process monitoring and controlling fully automated systems.
Audible Sensor Positioning Assistant. This intuitive system provides visual and audible indications while mounting the (paired) sensors.
Because of its bi-directional operation the KATflow 150 achieves the highest achievable accuracy with 0.5%.

This ultrasonic flow meter operates based on transit time difference technology. This makes the device highly accurate, providing reliable flow data for almost any liquid, independent of the electrical conductivity of the medium.
