Products overview:?
ZWS series - 100 f1Outside type ultrasonic flowmeterIs based on microprocessor technology, and its complete flow measurement instrument, compared with other conventional type flowmeter or other ultrasonic flowmeter, in addition to measuring installation is simple: the sensor on the outer wall of pipeline can measure the fluid flow, don't need a broken pipe installation, no pipe diameter requirements, but also has high precision, high reliability, high performance marked characteristics.Is by choosing the advanced large scale integrated circuit and advanced SMD SMT soldering process.To ensure that each factory of flowmeter has the same performance.Flexible Chinese show host wall-mounted (standard wall hanging F1, F2 explosion-proof type, plate of S type, hanging FN network) to meet different kinds of industrial field.Simple and convenient sensor field personnel to install and maintain easily.?
Second, the working principle:?
ZWS series - 100 f1Outside the bound type ultrasonic flowmeter using low voltage, pulse launch reception theory, adopting double balanced differential signal transmitting and receiving technology has nothing to do with hardware parameters design method;When the ultrasonic beam propagation in the liquid, the flow of the liquid produce small changes will make the travel time, the travel time is proportional to the liquid flow rate, the change of zero flow, two sensors is identical to that of the time required to transmit and receive sound waves (actual measurement of zero flow technology);Medium flow, the flow direction of sound wave transmission time is greater than in the direction of flow of sound wave transmission time.?
