ultrasonic water meters
                                                            

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
