1、Measurement Characteristics
Flow calculation model and temperature compensation algorithm are integrated in the modules.
2.Mechanical Assembly
Small diameter module(DN15/20 Brass Pipe)③
Small diameter module (DN15/20 Composite Material)
Small diameter module(DN15/20/25 Brass Pipe)
Assembly Importance： Make sure the spool piece is full of water, avoid bubble generating.
Water metering module needs to be combined with the user’s entire structure④to realize waterproof.
Interface wires⑤：
3、Electrical and Communication Interface
Power： Regulated power supply, in the range of 3.1V～5.5V, can provide 20mA peak current.
The higher power is recommended.
Communication Interface： UART, 3.0V, Baud Rate: 2400bps、Even parity check、Data bit: 8bit、Stop bit: 1bit.
UART TX can be used to wake up the user's board, falling edge active(abnormal state or change in cumulative flow per more than 1L@normal mode，
water flow every 1s@test mode, abnormalities).
After UART TX wakes up the user's board, UART communication can be performed after 100us.
Communication Command⑥：information read、setup and etc.
Power consumption：
4.Ordering information
GPxx = GP22/GP30/GP31 solution, DNxx = nominal diameter, YY = year, MM = month, DD = day, SSSSS = product serial number that day
For example：IA-UWM-1-GP30-DN15-181013-1234
Remarks
①Please contact iESLab if you select other flow range ratio.
②Please contact iESLab if you select T50 temperature class.
③DN15 shares most design with small diameter water metering module(DN20-DN40), more details please contact iESLab.
④For the reference design of the entire structure, please contact iESLab.
⑤Please contact iESLab for wiring method of other interface.
⑥Regarding the detail communication command, please contact iESLab.
⑦Water metering module without calibration parameter needs to be calibrated by the matching ultrasonic water meter calibration table. Please contact iESLab.
⑧Sample Applications as below.
