SmartHeat  9X-UR1000 Series Ultrasonic Heat Meter

9X-UR1000 series is a high performance ultrasonic heat meter from SmartHeat. Its key components include integrator, flowmeter and temperature sensor pair.

9X-UR1000 series supports standard M-BUS (European standard 1434-2007 conformance) communication functions.

9X-UR1000 series offers infrared meter reading function (when using with the meter reading instruments from SmartHeat).

9X-UR1000 series is based on the advanced multi-channel ultrasonic flowmeter, and offers higher accuracy of flow measurement. It features:

l  High accurate measurement

l  Good low flow

l  Configured as passing the central channel, and measuring symmetric and asymmetric flow state distributions

l  Reproducing the real flow by double integral on flow rate and section, and minimizing the integral error by function interpolation

l  Accurate time measurement technology, rapid measurement cycle and no effect of flow pulsation

l  Bi-direction metering

l  Big measuring range

l  Nominal size of DN25 to DN15000mm

l  Shorter upstream and downstream straight pipe runs required

l  Dry calibration (direct calibration) technology

l  No pressure loss

l  Self-diagnosis and redundancy technologies

l  Optional pressure transmitter and secondary meter display

Reliable sensor performance and service life of more than 10 years.
