Q:What if the intelligent water meter is not accurate?
Water meter is not private property, property rights owned by the water company, so there are problems in time to contact the property owner, to avoid unnecessary losses.
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.
Q:Service life specification of water meter
According to the National Technical Supervision Bureau issued the document No. [1991]374 regulations, 15 caliber 25mm life with water use shall not exceed 6 years, not 25 caliber 50mm more than 4 years, due to rotation. The industrial water meter is periodically tested, and the living water meter is only used for the first compulsory test, and the expiration date is rotated.
Q:On the trouble of household water meter
You remove the clean up dirt in the water can be recovered, the premise is to find water seals, seals can find water meter or property, of course, mean to say, the meter will not affect the water storage and water meter, a water meter is probably not more than one hundred yuan the price is according to your water meter diameter set.
Q:How many degrees is water on a water meter? Is that a ton of water on one side?
The last black figure is a few cubes, that is, a few tons (several degrees), and the red letter is 0.1 cubic meters. 1 cubic meters of water is equal to 1 tons of water. Under normal circumstances, the water meter records the flow rate and the flow is volume, so strictly speaking, the water meter is a measure of volume. The water on the water meter indicated that the water consumption was 1 cubic meters. Once on the water meter, it was 1 cubic meters, or 1 tons.
Q:How to see the new water meter
This is a rotor type cold water 20E type water meter, and the current water consumption is 32 tons! The three red pointers and the red number can be ignored. Just look at the black numbers! The present quantity of this watch is 32 tons! Accurate reading is 32.6704 tons! But the meter reading only reads black characters!
Q:Why can the high level intelligent water meter be equipped with a check valve that can not prevent the water meter from idling?
The air sac causes a greater amount of rotation in this case. Production process of tap water enterprises are open construction, in the production process of water dissolved gas, at the same time in the construction process, the pipeline will be brought into the gas pipeline, if the exhaust valve is unreasonable, gas cannot be ruled out well. Thus, if the house does not use water for a long time, or the pipe design is unreasonable, the highest point or the starting point of the pipe in the house will have an air sac. As we all know, the compressibility of gases is very high. At this time, if there is pressure fluctuation on the pipe network, the space expansion in the pipeline will be very large, so the water meter will rotate more. According to statistics, the resulting water is less than 2-3 m3/ months, and more will produce dozens of cubic meters of water per month. According to the report statistics, the existing users reflect the water meter rotation of the phone 26, after field investigation and treatment found that because of the table after the airbag inside the house and the rotation of 21 households, accounting for 80.8%, after the pipeline leaking 5. Therefore, at present, most of the water meter produces rotation phenomenon, all because the back of the tube in the air bag caused.
Q:Learn readings for meters, water meters, and gas meters
Magnification is the measurement multiple formed by the transformer and the traverse through it (for example, a 150/5 mutual inductor leads through it, 1 times the magnification is 30, passes through 2, the magnification is 15, passes through 1 of which is 10)
Q:How do you check the water meter?
Showing the value of comparison of water meter and work measure, determine the error inspection of water meter.
Q:How do I reverse the digital water meter?
First, the human factors in the reversing of the water meter, the manual bar, the reverse is man-made, and a few soil method is also very simple, as long as the water meter is removed, the installation can be reversed. The installation will make water meter readings go backwards, causing huge error meter measurement, a method which is currently the most direct fee evasion. Take a look at the external forces, the water meter upside down, the macro should be a kind of water meter rotation, so the cause of the water meter rotation is also applicable to water reversing.
