Energy measuring technology


KATflow 100





Heat meters
Ultrasonic flow meter for thermal energy measurement
KATflow 100 • KATflow 150 • KATflow 230

Three of the Katronic ultrasonic flowmeters can also be used to measure heat, as the need for portable and stationary heat meters is increasing in both the various industries and the public sector.
The clampable flow and temperature sensors enable non-invasive thermal energy measurements without process interruptions, pressure drops and leaks.

To use the clamp-on flowmeters as a heat meter, two PT100 temperature sensors are needed, as well as a pair of flow sensing transducers attached to a suitable pipe section. The temperature sensors are mounted at the inlet and outlet of the selected system. In order to determine the energy consumption, the device evaluates the flow rates and the temperature difference taking into account the specific heat capacity of the corresponding medium.

Measuring technology





The flowmeters KATflow 100 and KATflow 150 are designed for permanent installation in a variety of HVAC applications
and can be easily integrated into automated building monitoring systems. The portable KATflow230, on the other hand, is the perfect measuring instrument for on-site measurements in the context of energy consumption surveys. All heat meters have process outputs including power, open collector with totalizer pulse and digital relay.

In addition, the KATflow 100 and KATflow 150 can be equipped with RS485 and Modbus communication interfaces.
