- Q:Why is the water meter valve closed and solutions?
- When the remaining water reaches the set alarm amount, the screen shows "valve off"". Brush the user card to open the valve and continue to use the water until the valve is closed. Credit card is recommended to buy water as soon as possible.
- Q:How long can the smart water meter battery work?
- At present, the average static current of water meter module is below 3uA, and the total power consumption is about 970mA in 6 years. (the flow of valve switch is about 80mA/9s). This is only theoretical value, and there is no question about it. And if the pipe network is in the state of pressure (0.4Mpa), the current of the switching valve usually needs more than 90mA.
- Q:Where is the backflow preventer installed?
- Drainage facilities shall be installed in the installation area.Valve should be installed before the valve (butterfly valve) filter and rubber soft joint (or telescopic device), valve installed after the gate valve (butterfly valve).
- Q:How do you measure the degree of household water meters?
- Oh, this won't be. Look at the red one or the black one. I forgot, but it's not next to *1000, *100. Look at that one. It looks like black
- Q:What's the size of the household water meters?
- Household water meter is usually 15 or 20 caliber majority, there will be a small amount of 25, 32 of the water meter, water gauge caliber depends on the installation of the pipe diameter of the house, that is, usually 4 points, 6 in charge.
- Q:Why is the water meter always called?
- Reading water meters is generally pipe, there is pressure or gas will cause boiling water, pipes have sound.
- Q:How do water meters clean scale?
- Go to the daily necessities store and buy some oxalic acid to wash it. That's OK
- Q:Has the number of water meters been accumulating? Should the water use of this month be reduced by last month? Will it be cleared?
- Yes, the number of water meters has been accumulatedOnce the water meter is checked, the water meter is used to calculate the water consumption by subtractingIt is generally not cleared
- Q:50 of the wire water meter with a large head to undertake, the joint wire mouth how much? Is it 50?
- 50 meter socket is 50. But the name of PPR is different from that of water meter.
- Q:Water pressure is too large, water meter will be deviation?
- The flow velocity is smaller when you pressure household water pipeline with strong water flow meter beat again.
