- Q:Why should the water meter be horizontally installed?
- Experts say, many users in order to save money or limited installation position, the water meter import and export pipe length is not enough. The correct installation is 15 mm caliber water meter, upstream of at least 150 mm downstream straight pipe, there should be at least 75 mm straight, otherwise it will because of the flow of "full of twists and turns and affect the measurement accuracy of water meter. In addition, the tap water, such as mixed air, excessive impurities and dirt from the pipe wall, will affect the accuracy of water meter measurement
- Q:Water tonnage data show a sudden increase in a lot of what is the reason
- Water tonnage data show a sudden increase a lot, because of a sudden massive water pipe leakage, and leakage occurred in after the location of the water meter. If the investigation, you can follow the water meter to the direction of the tap to find, in order not to cause miscarriage of justice, you can first turn off the water meter.
- Q:What is the rate of installation of water meters?
- A scale measuring rate of 100% two meter f (rate = two level table and a table of water / water) x100%.
- Q:Is there any deviation in the water meter measurement? Why?
- Water meter is the only measuring instrument for the water supply enterprise and the user to settle the trade. It is the main basis for the water users to collect the water fee. The deviation of water meter measurement will have a negative impact on water supply enterprises to improve water rate recovery and reduce production and sale rate, and will easily cause disputes between water supply enterprises and users. Talking about the causes and Countermeasures of metering deviation of water meter in light of practice.
- Q:The differences between electromagnetic water meters and ordinary water meters, as well as their respective advantages and disadvantages
- Electromagnetic water meter is designed for the actual requirements of water supply enterprises. It can optimize the water supply and ensure accurate water trade measurement and settlement. It conforms to the GB/T778-2007 new water meter standard. Electromagnetic meter for stainless steel shell design, ensure water use in high pollution corrosive environment, in line with domestic water use environment, full structure, zero pressure loss, no wear; ultra large range, small flow sensitivity and large flow measurement is far superior to the ordinary traditional water meter. The remote monitoring and management software system supporting the use of electromagnetic meter with remote transmission function, can not only realize the data receiving, storage flowmeter can also realize the statistics and analysis of data flow, can facilitate the timely control of the water flow in the region of each measurement point. The disadvantage is that its higher prices, complex structure, power to normal use.
- Q:Can the figures on the water meter be changed?
- Remove the table: find a water unit worked in friends, help to remove the table, unscrew the four screws inside the stopwatch readings, then put on a table, this number on the meter will turn very slowly. Do not advocate this method, because this is in violation of the household water convention, and do not understand the demolition of the table, it is easy to damage the water meter.
- Q:There are two valves at both ends of the water meter. I know that the valve at one end of the water meter is a water valve. What's the other valve for? Open, there will be exhaust noise
- The front valve controls the pipe in the home for the user. After the table valve is the encryption valve, to use special tools to open. Maintenance water meter. Debt prevention.
- Q:The backflow meter will not turn
- Water meter, good water meter is not to turn, and some not very good will turn
- Q:Why doesn't the water meter turn around?
- Subsurface leakage. If the water consumption exceeds the normal value of more than doubled, renovation concealed, installation pipe leakage or indoor pipe network underground dark leakage possibility is bigger, especially pay attention to whether the toilet is flowing.
- Q:What's the procedure for water meter transfer? What documents do you need?
- Tap water limited liability company audit and site survey data.
