Q:It is normal to add a valve before the water meter
Water meter after the valve is easy to maintain. Easy to change tables and no water. In front of the valve with little significance. And waste. But when it comes to formal, plus a check valve in front of the table, that is the normal installation. Can prevent water meter reverse!
Q:Difference between vertical and horizontal water meters
The shape is different, the vertical can be mounted directly on the riser, and the flat is installed on the horizontal pipe. The rest of the flow points are the same.
Q:What about rust on water meters?
Rust and scaling in water meters are caused by many reasons, such as rusting of pipes, etc., which occur in the extended use of water meters (the state provides a period of 6 years for the use of water meters). In this regard, we suggest changing the water meter or re cleaning and testing the old water meter. At present, the case of electrostatic spraying process, with its strong adhesion,The utility model has the advantages of strong corrosion resistance, smooth paint surface, etc. the utility model effectively solves the defects of the rusting in the table, and prolongs the service life of the water meter, together with the reading is more clear and straightThe digital representation of the dial, the problem of missing the count, will be completely solved.
Q:How much water can be overdrawn by a cassette meter?
1, adopt contactless IC card patent technology, transmit data on the outer wall of water meter by wireless mode, solve the problem of waterproof, moisture-proof and anti attack.2, zero power consumption patented technology, so that the battery life is greatly improved, to ensure that the use of more than 8 years.3, electric suspension ball valve patented technology: with anti lock, no fouling features, you can achieve small pressure loss, small wear, power consumption, rust prevention, anti blocking effect.4, valve automatic blowdown, anti blocking, anti rust Technology: automatic timing switch valve, instantaneous momentum of effective use of pipeline pressure caused by water, automatic blowdown of the valve, the valve to avoid rust, scaling.5, full seal design: all lines are sealed by epoxy resin, without exposed electrodes, good sealing.6, anti electric and magnetic attack technology: when from outside for strong electricity and magnetic attack, water meter will automatically shut the valve.
Q:The plastic lid on the water meter has fallen off. Can you match it?
Not for sale. For example, filling liquefied petroleum gas relief valve, if the rubber pad lost, buy a 5 cents only. But you can only earn 10 Fen if you buy one. So, stores only sell the new valve, a net profit of 5 yuan. Those who do not have to buy a new one.
Q:Why must water meters undergo strong inspection?
Quality supervision department staff explained that this is because with the increasingly shortage of water resources, water costs continue to improve, the accuracy of water meter measurement more and more attention to the masses. In addition, if the water meter is not maintained and maintained for a long time, the accuracy of its measurement can not be guaranteed.
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:Smart water meter no electricity, how can I do, the battery can change it?
This kind of water meter commonly uses the meter special-purpose lithium battery, generally does not sell, if the property (running water company) has the spare battery or the spare meter then, may nearby let them change.Not recommended himself to replace the battery, a battery is not easy to find, but the water seal, not to unseal, if this thing is fine it's not worth it.
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: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.
