- Q: What is the nominal flow of water meters?
- (1) the nominal flow rate of DN15 is 1.5 m3/h;(2) the nominal flow rate of DN20 is 2.5 m3/h;(3) the nominal flow rate of DN25 is 3.5 m3/h.Some water meters on the subject of "N2.5" refers to the "water meter nominal flow Qn is 2.5 m3/h", from which we can know that the water gauge's caliber is DN20. (nominal flow, some people are accustomed to commonly known as flow)
- Q: Which kind of water meter is more convenient for large-scale projects? The best engineering case can refer to
- For the newly built large-scale projects, the ordinary mechanical water meter has been unable to meet the modern management requirements. Intelligent water meter becomes the first choice
- Q: My water meter dial has a big bubble, bubbles move, flower needle on the turn (no water in the home), there are bubbles that normal, there are said to belong to the water meter is defective
- The bubble is normal does not affect the use of dynamic pressure meter bubble that loss of pressure loss flower needle rotation but not fast that your neighbor has water you look at the bubble sometimes sometimes small bubble big your water pressure
- Q: The differences between electromagnetic water meters and ordinary water meters, as well as their respective advantages and disadvantages
- The internal structure of the ordinary water meter (traditional water meter) can be divided into three parts: shell, sleeve and inner core from the outside. The shell is cast iron. The inner core is divided into three layers: upper, middle and lower, and the upper layer is visible from the glass window, with only pointers and dials. In fact, the most critical is the lower layer, there is a plastic wheel inside, and there are many plastic blades on the side of the wheel. It is called "impeller"". The water impacts the blades around the wheel, generating torque and rotating the impeller. The bigger the tap, the faster the flow, and the faster the impeller turns. The advantages of an ordinary water meter are simple and inexpensive. It can be used for a long time in a humid environment without maintenance, and without power supply. The power failure does not affect the work, so it is still widely used.
- Q: What's wrong with a water meter with a flange connection?
- Flange connection is an important connection way for pipeline construction. Flange, threaded connection (wire), flange and welding flange. Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different. According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad. Flange connection, easy to use, able to withstand greater pressure. Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.
- Q: The difference between rotary vane water meter and screw wing water meter
- Rotor type water meter rotor type water meter is suitable for small diameter pipeline unidirectional flow measurement. Such as total household water metering caliber 15mm, 20mm specifications of pipe. The water meter is mainly composed of a casing, impeller measuring mechanism and a retarding mechanism, as well as indicator, has the advantages of simple structure characteristics.
- Q: What's the tool for changing water glass?
- Then independent meter for the glass cover, you can not get any professional tools, only a small hammer. Find the water above the golden copper lid four lobes (ear) the most stout, gently tapping with a hammer, with patience, action to light, otherwise it will knock on the fracture may of course angle, the rest of the three corners of the best turn out of a few, a full range of shock and loose best. Light knock on a corner of the copper will break the weak. It is an important direction, counterclockwise or clockwise, one that is not good, and generally seems to be with words (such as 15MM) arrow in the opposite direction, tapping (must be light, slowly) a few will be released, not to knock on the side, is a hammer knock, and as close to convex the root of knock, with a round wall slide better, so as to better reduce the salient sections of excessive force to fracture problems. Of course, if you can't hit it, change it in a different direction. Only about two directions should be used flexibly. The above operations must pay attention to the integrity of the above copper cover ears, even if only one of the four knock off, the tightening force is much lower, will definitely affect the tightness, the basic copper cover will be scrapped.
- Q: How do you connect the water meter with the PPR tube?
- First determine the interface diameter of water meter, the general domestic water meter interface is 15; buy a PPR live connector, which is a section of PPR pipe to do with the connection, the pipe and the connector can be connected.
- Q: Before the water meter, where does the water meter refer to the end of the water meter?
- The section of water flowing into the meter is the front end of the water meter, and the section out of the meter is the back end of the water meter.
- Q: Why should water meter use batteries?
- Because of the use of intelligent water meters or remote data water meters, electrical energy is needed to transmit data signals
