Q:Water meter check valve, front and rear should be installed according to it?
Generally installed after the water meter.The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter.
Q:The total water meter and the total value of the water table vary greatly
This is normal, the sensitivity of the water meter is not the same, the same flow, the high sensitivity of the water meter will turn, and the low sensitivity of the water meter will not respond. There may be leaks in the pipe, especially where the pipes are joined.
Q:What is the rate of installation of water meters?
Three level meter rate = (three level water quantity / two class surface water quantity) x100%. One or two, three class water meter measurement rate refers to the factory (company), workshop, class (section, equipment) water meter measurement rate
Q:The water meter is too big
Water pump pumping from the table, resulting in accelerated flow of water before the table, forming a relatively jet phenomenon, affecting the normal measurement of water meters
Q:How does a water meter work?
Is actually very simple, because the water meter shell is fixed, the internal volume is fixed, and the water is flowing, it promotes a rotation of the impeller, the impeller when rotating a circle, there is a constant volume of water. Therefore, as long as the number of turns of the impeller is accumulated, multiplied by the constant volume, the total flow can be obtained.
Q:Advantages of intelligent water meters
The water consumption can be controlled according to the contract, and the water price of the ladder water price can be automatically calculated, and the data storage function of the water can be carried out simultaneously;
Q:Water meter display, replace the battery after water, why not start after the card water meter?.
When the user card is inserted, the display will display the amount of water purchased, the amount of new available water and the total amount of water used in turn.
Q:Does the new water meter go slower than the old one?
The water meter is not slow, the old water meter has been used for a long time, because of the mechanical friction between the gear and gear, the resistance increases. The new water meter because the indicators and mechanical gears are very good, so the measurement is more accurateAccording to what you say, if the slope is not very large, there is little effect on the speed of the water meter, but the horizontal water meter does not meet the specifications of the water meter installation if it is inclined to mount
Q:What is the nominal flow of water meters?
(1) the nominal flow rate of DN15 is 1.5 m3/h;(2) the nominal flow rate of DN20 is 2.5 m3/h;(3) the nominal flow rate of DN25 is 3.5 m3/h.Some water meters on the subject of "N2.5" refers to the "water meter nominal flow Qn is 2.5 m3/h", from which we can know that the water gauge's caliber is DN20. (nominal flow, some people are accustomed to commonly known as flow)
Q:The water meter in the taxi house is broken. Who will fix it?
Table Water Leakage belongs to the tap water company responsible for maintenance, can make local tap water company repair phone repair, or find the property to handle.
