Q:How to see the number of IC card intelligent water meter
If your water rate is double rate, after you insert the card, the remaining water charge is displayed on the LCD screen,
Q:50 of the wire water meter with a large head to undertake, the joint wire mouth how much? Is it 50?
50 meter socket is 50. But the name of PPR is different from that of water meter.
Q:Is there a national standard for the metering accuracy of tap water meters?
The measuring accuracy of water meter has national standard.
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:Types of water meters
Velocity meter: a water meter enclosed in a closed pipe, consisting of a moving element, which is directly moved by the velocity of water flow to obtain power and speed.A typical speed water meter has a rotor type water meter and a spiral wing type water meter. There are single beam water meter and multi stream beam water meter in the rotor type water meter.
Q:What is the characteristic flow of a water meter?
Overload flow: water meter in a short period of time, and without damage, the maximum use of flow, the value of two times the usual flow.
Q:Who is responsible for the lack of water meters leading to more water use?
The pipeline pressure fluctuation. Water as a liquid, there can be compressed in water supply pipeline pressure is high. The pressure fluctuation is inevitable in tap water pipeline, when the pressure of the main network rises, after the water in the pipes because of increased pressure and volume reduced, this will have the trace of water through the water table generation is transferred, inversion pressure net charge reduced. Because water resistance is greater than the internal gear is reversed when forward resistance, even if the same amount of two water meter, water meter is reflected in the reading on the will also have differences, the total performance is positive.
Q:Is there any deviation in the water meter measurement? Why?
The problem of water gauge over time: water meter should be checked regularly and replaced at maturity. (1 meter) when in use, the rotation of the impeller and the top friction frequently, while the top is an important component of water meter support within the rotation of the impeller, which is the result of a top wear between the top and the impeller friction resistance increases, the water meter is negative; two impeller position decreased, increased between the impeller and the impeller box resistance decreases the water meter is partial. (2) in water use, due to non-uniform distribution of water meter, water flow flows through the impeller inlet box side flow is greater than the water outlet side, one of which is that the middle and top impeller impeller sleeve frequent friction, tilted to the side edge of the water outlet, impeller and impeller parts box wall close, increasing resistance at the same time, the impeller diameter by grinding, water impact on the impeller torque is small, the water meter is negative; two upper middle and upper impeller sleeve is inclined to the water outlet, the upper splint sleeve is frequent friction, into an oval, the impeller axial shift, wear between the impeller shaft and gear box, to make the resistance increase also, partial negative water meter.
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:The role of water meters
An instrument for measuring water flow. The cumulative flow of water is mostly measured.
