STUF-280W ultrasonic water meter is the latest innovation from Shenitech. It employs cutting-edge technologies on ultrasonic flow measurement, digital signal processing (DSP) and surface mounting electronics. The sensor body is made by bronze. It has no moving parts, thus, is literally maintenance-free. The sensor is straight-through type, no blockage exists. This not only leads to very small pressure drop, but also allows the meter to work with both pure water and water with some solids.

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.

Unlike mechanic water meter, STUF-280W water meter has outstanding long-term stability. The performance of its sensor does not degrade over time, thus, its overall system accuracy does not degrade over time. 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 (Pulse, M-bus or RS485 output). The large display can be set to display flow velocity, flow total, working time, etc.

STUF-280W ultrasonic water meter represents the trend of modem water metering industry. Both commercial and residential installations can profit from the advantages of wear-free water measurement: precision, operating security and long service life.

Operating Principle:

A typical ultrasonic water meter consists of a sensor and an electronic console. The sensor has two ultrasonic transducers (A and B) built into its body. Each transducer functions as both ultrasonic transmitter and receiver. The electronic console operates the two transducers by alternately transmitting and receiving a burst of sound energy and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the water in the pipe. The flowrate is calculated from the measured velocity and the pipe inner diameter.
