THE SONOTHERM SN3070 ultrasonic heat/cold water meter
SONOTHERM SN3070 heat/cold meters are intended for measurements of absolute heat/cold quantities delivered to customer plants or otherwise consumed in closed hot water heating/cooling systems. When used as commercial meters, they can be located either at the input hot-water piping to heated buildings or premises, or at the output of heat sources before a heat exchanger.
The SONOTHERM heat/cold meter measures and stores information on heat quantity calculated from the water temperatures measured at the input and output piping by means of coupled resistance temperature sensors Pt 100 (Pt 500) and the heating/cooling water flow-rate measured by an ultrasonic flow meter.
The heat/cold meters of the SONOTHERM SN3070 series are supplied in the following configuration:
- electronic unit MTU2.00
- coupled resistance temperature sensors Pt 100 (Pt 500)
- ultrasonic sensor UC7.0
