Applied with Euro standard of EN1413, battery powered ultrasonic water meter is a super low power consumption water meter with high-accuracy industry electronic parts equipped. It has many advantages such as: high accuracy, good reliability, no moving parts, no pressure drop, Low maintenance, etc. It is a excellent substitution of other water meters. With high quality parts and advanced technology, the ultrasonic flow meter has reached a very excellent performance.
Unlike mechanical water meters,the ultrasonic water meter has an outstanding long-term stability. There is no moving parts in its sensor, so its performance doesn’t degrade over time,its overall system accuracy doesn’t also degrade over time.
Features:
(1) Measuring accuracy: ±2% or 3% of reading value
(2) No pressure loss and no moving parts, designed for no maintenance
(3) Measuring pipe founded by mould, no discharging
(4) IP68 protection class, workable under 2 meter depth of water
(5) Low start-up flow rate, the lowest flow speed measured is 0.03m/s
(6) High temperature resistant and abrasion resistant transducer, working temperature －40℃~150℃
(7) RS485 port, support MODBUS,M-BUS,etc
(8) Integrated type and none integrated type
(9) Ultrasonic time-difference principle
(11) Measuring period: 10S
(12) Power supply: battery powered and DC8-36V. Battery can work for 4-5 years.Battery is 3.6V/19AH(>=2.6V for normal work)
(13) Horizontal display and Down-looking display
(14) Integrated inversion and separating version
(15) GSM remote data reading
(16) Seperating version support clamp-on type and insertion type transducers.
(17) An ideal choice for installing place without external power source
