1. Reasons for inconsistency between on-site and remote transmission of flow meters
Flow meters display instantaneous and cumulative flow rates. If remote transmission signals use 4-20mA or pulse signals, there will be certain errors in the conversion of remote instruments, resulting in inconsistent instantaneous flow rates (generally not much difference). However, using 4-20mA signals for cumulative quantity calculation will be completely different from the on-site cumulative quantity, not only caused by errors, but also by different starting points for accumulation. If you want the remote instrument display to be completely consistent with the on-site instrument, the training personnel need to transmit it remotely through the same communication method.
2. How to open the valve of a gas remote flowmeter
There are three main ways to close the valve of a gas remote flowmeter: remote control, local manual operation, and IC card control.
. 1. The gas company remotely controls the valve opening by sending valve opening instructions to the flow meter through wireless networks such as GPRS or LoRa through the backend management system. This is mainly used for users to restore gas supply after paying fees, or for unified remote management. 2. Local manual valve opening requires opening the equipment protective cover and using tools (such as screwdrivers) to operate internal buttons or knobs to open the valve. This method is a backup solution for remote system failures or on-site maintenance and debugging. 3. IC card valve opening: Users insert the recharged IC card into the meter card slot, and the device automatically opens the valve after card reading verification is passed. This is commonly used_600x400.jpg)
