Ultrasonic heat meter CRLB-A
The heat meter CRLB-A combines state of the art microcomputer technology with innovative ultrasonic metrology avoiding any moving mechanical parts.
This technology is therfore non-wearing and largely maintenance-free. High accuracy and log-time stability ensure correct and fair heating cost accounting.
The quantity of heat output from the heating water is proportional to the difference in temperature between the supply and return temperatures and the volume of heating water having flowed.
The heating water volume is measured by an ultrasonic pulse that is first sent in the direction of flow and then aganst the direction of flow.
With the flow the signal transmission time between the transmitter and reciever is reduced and against the flow it is increased.
The volume of heating water and the temperaute difference between the supply and return are then multiplied and the product is added to the running total.
The result is the quantity of heat consumed. This result is recorded and displayed in physical units kWh/Mwh.
