Ultrasonic prepaid large-diameter water meter
The ultrasonic prepaid large-diameter water meter is a high-tech electromechanical integrated intelligent water meter developed by our company. It is a highly intelligent instrument composed of advanced microcomputer control technology as the core and IC card technology as the information transmission medium. The instrument is based on an ultrasonic water meter and is equipped with a new type of low-power, high output torque non pressure loss motor control valve (pilot valve or butterfly valve) and a microcomputer controller. Adopting advanced logic encryption technology and implementing one meter, one card system ensures the security and reliability of user data.
Main features:
◆ Prepaid function: Users can purchase water before use, and if they owe, the valve will be closed to stop the water supply.
◆ Dual LCD synchronous display function: Ultrasonic LCD display and prepaid LCD display are synchronized.
◆ Alarm function: Battery undervoltage, insufficient available water, strong magnetic interference, and other fault information will prompt an alarm on the LCD screen.
◆ Data upload function: Every time a user purchases water, relevant information will be brought back to the management system, allowing the management to understand the user's water usage situation and the status of the meter.
Valve self maintenance function: The valve rotates at regular intervals to promptly remove valve scale and ensure valve flexibility.
◆ Anti hoarding function: The software allows for flexible setting of recharge limits to prevent users from hoarding water.
