Descriptions:
With its maximum 95 °C operating temperature and nominal pressure of 1.6MPa, the technical specifications meet the standard for residential meters. The high measurement dynamic allows a load of up to double the rating, thereby ensuring high operating security.
Reliable Ultrasonic Flow Measurement
The STUF-280Tx uses transit-time ultrasonic flow measurement principle to measure the flow rate: opposite sending and receiving transducers send ultrasonic signals alternately with and against the flow direction. The flow rate can be exactly calculated from the difference between the two transit times. There is no moving part in the sensor. Thus, the measurement is wear-free and stable over a very long time period.
Suitable for Both Commercial and Residential Applications
This compact meter fits in even the smallest installation conditions and can be mounted separately from the electronics console. The meter also has an order option for remote read-out (M-bus or pulse output). The large display can be set to display heat consumption, temperatures, flow total, working time or velocity.
Remote Readout System for building energy management
When equipped with M-Bus module, as more as 500 heat meters can be networked through a two-wire bus to a central location for integrated resources management. An optional concentrator and data acquisition software make the whole system installation and integration easy.
