1. Introduction
WM9100-EV Prepaid Ultrasonic Water Meter and WM9100-ED Digital Ultrasonic Water Meter are types of water meters which can measure and display the flow rate according to the time difference between upstream and downstream when the ultrasonic wave propagates in the water.
The Ultrasonic Smart Water Meter producted by Lanry Instruments can be equipped with wired or wireless data communication interface to communicate with the collector, concentrator or network server to form a remote meter reading management system. The management department can copy the data in the table as needed and convenient to the user's water consumption statistics and management.
● 10 years shelf life battery.
● With stainless steel (SUS304) body.
● With the turn-down ratio as R250, R400 for optional.
● No moving parts, excellent long-term stability and reliability.
● Bidirectional flow measurement (forward & reverse).
● Integrated valve with prepaid type is optional.
● Standard output: RS485, M-bus, LoRaWAN and NB-IoT.
