LAISON Walk-by Wireless Reading Water Meter AquaLink (Hereafter mentioned as AquaLink) is developed basing on LoRa RF Wireless Com. Technology from Semtech (https://www.semtech.com/), features in long communication and low power consumption for Automatic Remote Water Meter Data Collection while driving or walking along the street. The default LoRa RF Wireless Com. Frequency is 470MHz, and can be customized to 433MHz, 865-867MHz, 912-915MHz etc. as request by different countries. The basic water meter parameters like Total Consumed Water Volume, Instantaneous flow rate, Meter’s Real Time Clock (RTC), Battery Voltage etc. could be collected and store to LAISON MDT (Mobile Data Terminal) and uploaded to Center System via GPRS or WIFI for further analyzing.

LAISON GPRS Bulk Meter System consist of Mechanical Bulk Water Meter with Pulse Output and Data Remote Terminal Unit (Hereafter referred as “DataRTU”), which connect to the water meter via pulse output and upload the meter’s data to Center System via GPRS automatically. With user friendly interface, Customers could also query / set the corresponding parameters in meter via SMS on Mobile Phone.

Ultrasonic STS AMR Water Meter measure water flow by detecting ultrasonic beam when the water velocity changing, analyzing ultrasonic beam to measure water velocity to draw a conclusion that the water discharge. It has high accuracy reach to R200, and would not measure air, not be effected by sand. It has Real-time clock (RTC), real-time volume calculation & monthly billing data etc. functions to provide real-time water consumption statistics. Meanwhile it has Friendly Period management function to ensure the water use in holidays and duty-off time Periods as human-based management of water supply.

Electromagnetic flowmeter is composed of the sensor and converter, and the sensor consists of measuring tube, electrodes, excitation coils, iron core and shell and other components. After the traffic signal is amplified, processed and operated by converter, you can see the instantaneous flow, cumulative flow, output pulse, analog current and other signals for the measurement and control of fluid flow. PMF series electromagnetic flowmeter adopts the smart converter so that it not only has the measurement, display and other functions, but also supports the remote data transmission, wireless remote control, alarm and other functions.
