Q:After the heat exchanger is installed, no tap water is needed. How can the water meter be turned?
It's bad. Your heat exchanger leaks
Q:Is the water meter really drip proof?
Ordinary water as the rotating components and counting gear movement inertia, so in the process of measuring, if the water flow is small to a certain extent to promote the movement of the impeller and the counter gear, thus the micro flow cannot be measured, people can use this drip less than starting flow of the water meter measurement of access to tap water the water pipe network, so that the water supply enterprises suffered losses.
Q:How can the water level of the water meter be adjusted instantaneously?
When the meter is repaired, it should be signed by the management to confirm the current readings. To the back, you have to turn off the water, remove the seal, remove the glass cover, and then pull out the pointer to the original reading, but if you secretly this involves stealing
Q:How do you calculate the water meter inversion?
In short, the problem of water table rotation, although the national standard says that the water meter rotation within a certain limit is allowed, but the inverted water meter is completely uncontrollable. At present, only control to avoid the occurrence of water meter rotation, such as the installation of exhaust valve and check valve, so as to maximize the water meter to avoid rotation.
Q:Which direction is the switch for domestic water meter?
It's a watch side valve. Generally speaking, the counter clockwise is open. Be careful not to force too much, easy to spool broken.
Q:The difference between rotary vane water meter and screw wing water meter
Rotor type water meter rotor type water meter is suitable for small diameter pipeline unidirectional flow measurement. Such as total household water metering caliber 15mm, 20mm specifications of pipe. The water meter is mainly composed of a casing, impeller measuring mechanism and a retarding mechanism, as well as indicator, has the advantages of simple structure characteristics.
Q:How long can the smart water meter battery work?
And the total capacity of the battery is not the actual value available, the average best battery, that is, 80% of the battery capacity. With the use of late, internal resistance increased, power consumption is also increasing.General manufacturers use for lithium battery with capacity of 2000mAh, the actual available capacity is about 1200-1300mAh, according to the water quality and the use of different users have many differences in 3-6 years for the more common case.
Q:The water meter doesn't move. The pump keeps beating. Why?
If it is a pump problem, check the following items:1) if the pump outlet pipe has a pressure gauge, or suction pipe mouth has a vacuum meter, calculate the sum of the two, whether or not close to the head.2) observe the pump housing bearing whether there is a large number of leaks, if there is, please check the leakage ring and other sealing devices3) check the pump blade whether there is excessive damage, such as cavitation4) check whether the blade is correct or not5) check the pump mounting height, the height is greater than the allowable suction height (centrifugal pump, 5~7, m) if it is self Jiezhuang pipeline pump should pay special attention to this problem, the height is not more than 2~3 residential floor height. For example, the third floor does not need to install the pump, may have the water, then the pump installs the highest not to be able to exceed six.6) check that the suction port is blocked7) check the suction pipe whether there is greater hydraulic loss
Q:Why doesn't the water meter turn around?
User small flow drop. Many users believe that a drop of water will not measure, but the water pressure caused by dripping water is lower than the pressure of water supply, which leads to pressure fluctuation and the water meter is slightly changed.
Q:What should I do when the water meter is turned upside down?
The reverse of the water meter is because there is air in the water pipe. You can open all the taps and drain the air out.
