Mechanical remote water meter (non-valve controlled)

Mechanical remote water meter is a kind of remote water meter developed by our company which is convenient for remote meter reading and control. Our company's mechanical water meter is adopted as the measurement basis, and NB-IOT narrow-band cellular Internet of Things is used to connect things, so as to realize automatic remote meter reading of the water used by the water meter.

functional characteristics:

● Alarm function, the remaining amount is insufficient, prompt users to recharge in time

● With low battery power, strong magnetic interference and other fault information reminder function or close the valve reminder

● Data in the table read back function, users can bring back the remaining amount of information after the card brush table

● Display function, user number, table number, signal quality, residual amount, cumulative amount, recharge amount, system information, alarm amount and other information can be displayed through the LCD screen

● Valve automatic maintenance function, valve every 15 days or so to switch once, timely cleaning valve scale, to ensure the reliability of the valve

● Prevent valve leakage function: after closing the valve, if the valve is damaged and not closed the valve, it can still be measured normally, and the remaining amount can be taken in negative numbers. Users can buy water again by swiping the card, and the remaining amount of water will be deducted automatically

● With NB-IoT communication function, the data is uploaded by the way of active reporting

●NB-IoT actively triggers data upload, which can be actively uploaded via RF card/touch button

●NB-IoT instruction delivery, instruction can be cached in the platform side to wait for delivery, wait until the table upload number of instructions will be sent to the table

● RF card and NB-IoT can sell water at the same time without affecting each other
