RBBW DN50-1000 District Ultrasonic Water Meter(Bulk Water Meters) is an innovative flow meter with static flow sensor based on the ultrasonic measuring principle. RBBW Ultrasonic Water Meter utilizes ultrasonic measuring methodology and microprocessor technology. All calculation and flow measuring circuits are designed on one single board, thus offering exceptional accuracy and reliability.
District Ultrasonic Bulk Water Meters (DN50 to DN1000) Features:
- Approved according to GB/T 778-2007 and MID certification(DN15 to DN600)
- IP68 of the whole meter, for each unit of the meter is IP68 designed; mounting, immune to any impact on measuring and pressure dropping to a minimum meanwhile
- Abnormal water usage alarm
- Water temperature detection, low temperature alarm
- Low starting flow rate, minimum flow rate is 1/3 traditional water meter
- High-precision machining centers, initiating action to prevent the occurrence of product non-conformity, stable and reliable
- Adaptable to inferior water quality, low in maintenance cost
- Ultrasonic etection
- Low initial flow rate and min. flow velocity measured is 0.002m/s;
- No mechanical moving parts, long service life
- Ultralow power consumption, battery with over 10-years(DN15-40) & 6-year life time(DN50-600 Flanged type); less than 0.0008W
- Support optical, RS485 and M-BUS(reless) communication interface; available in remote reading(AMR), and easy for central control and management
- Complies to MODBUS RTU and EN13757 communication protocol
