FR-500W Ultrasonic meter

    The drinking water
    The water treatment industry
    Water - heating
    Gasoline, diese
    The initial velocity is less than 0.01m/s
    Fluid dual channel measurement, improve the accuracy of
    The measurement period is 1 second, and the test time is 4 seconds.
    Built in lithium battery, battery life can reach 6 years or more
    IP68 protection grade potting movement, can work for a long time under water
    Support and support a variety of communication protocols, can realize wireless remote transmission
    Steel casting shell meets international new urban water conveyance standard
    The core device MCU, amplifier, two or three pole tube are all imported products, high performance, more powerful

FR-500W ultrasonic meter double channel and single channel choice, advanced liquid measurement technology and low cost of transmitter package combined together, the transmitter can be installed on the measuring point. Because of no moving parts that require little maintenance, and provide the running state of the long term drift of freedom and support is reverse flow measurement, set a variety of flow unit, infrared communication interface, support CJ-188, M-BUS multi protocol; single channel ultrasonic meter has a large span ratio, double channel of stratified fluid measurement can improve the measurement accuracy, widely used in urban water supply pipe, a household with water tables, water resource monitoring and also used in a variety of industrial field, matching wireless power supply and multiple communication interface, so as to realize the remote meter reading, FR-500W is widely used in the domestic and international water industry.
