Q:What sort of water meters do you have?
It is divided into cold water meter and hot water meterAccording to the medium temperature can be divided into cold water meter and hot water meter, the water temperature 30 degrees is its dividing line(1) cold water meter: medium lower limit temperature is 0 degrees, upper limit temperature is 30 Celsius water meter(2) a hot water meter: a water meter with a lower dielectric limit of 30 DEG C and an upper limit of 90 DEG C or 130 DEG C or 180 DEG C
Q:How often is the water meter checked?
In accordance with the relevant provisions of the state, with its first life meter compulsory verification of the effective period is defined as: the caliber of 15 - 25mm (15mm, 25mm), the use of the term may not exceed 6 years; the caliber of 25 - 50mm (25mm, 50mm), the use of the term may not exceed 4 years; diameter greater than 50mm, according to 25-50mm the requirements of the implementation. The qualified water meter shall be affixed to "calibration certificate" label and add after the first inspection sign seal "".
Q:How do water meters clean scale?
1. Let the maintenance personnel clean or clean the scale in the water meter.2, water meter screen surface, a few drops of detergent can also be.The water meter is a kind of measuring instrument, above a user can not be opened, unopened scale cannot be cleaned in the water, only tap water company maintenance personnel to remove water meter.
Q:What is the maximum water quantity of a water meter with a diameter of 80mm?
Water meter with a diameter of 80mm, the maximum water quantity is 80 cubic meters / hour.
Q:Why does the new water meter have no accuracy grade and where is the accuracy level of the water meter?
The accuracy level and measurement level of water meter are two concepts. The accuracy grade provides the indication error limit of water meter, and the 2 stage indicates the maximum indication value of water meter, and the error can not exceed 2%. The new procedure has 1 meter water meters, but it must be marked on the water meter. Measurement level is divided by the demarcation of the water gauge and the minimum flow rate to characterize the sensitivity of the water meter. The old rules are graded according to A, B, C and D, and the D level is the highest requirement. New procedures, dosage, process ratio (Q3/Q1) to replace the original level of measurement, the ratio of at least 20 options, the greater the ratio, the higher the requirements, the greater the difficulty of manufacture. The Q3 and Q3/Q1 values of the water meter are determined by the manufacturer according to the market demand, and must be clearly marked on the water meter. When the water meter is checked, the flow point can be selected according to the value indicated on the meter.
Q:What is the metering rate of a water meter?
1, level meter measurement rate: 100%2, two meter rate = two level table and water level, water table requires more than 90%;3, three meter rate = three / two of the water table and table water level requirements of more than 85%;
Q:The valve in front of the water meter is out of order and will be replaced by the owner or the property
In fact, you change a ball valve is also more than 20,
Q:What is the rate of installation of water meters?
Three level meter rate = (three level water quantity / two class surface water quantity) x100%. One or two, three class water meter measurement rate refers to the factory (company), workshop, class (section, equipment) water meter measurement rate
Q:How does Hua Xu IC card intelligent water meter sound for long time?
There may be little money left! If it is prepaid IC card water meter, there may be no battery! The problem is to understand what type it is! To make a judgement!
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.
