Q:It is normal to add a valve before the water meter
In principle, the water meter is not added before the water meter, because it is afraid of stealing water, the water meter is added to the water meter after the meter is added, and the water meter is provided with a main valve, and the water meter has a low failure rate
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
That's OK. It's normal and doesn't affect water usage
Q:Which direction is the switch for domestic water meter?
You should say that the valve is hand wheel gate valve, they are right, should be counterclockwise rotation, the handle can open. Otherwise it closes.
Q:Why can the high level intelligent water meter be equipped with a check valve that can not prevent the water meter from idling?
The cause of the rotationThe problem of water meter rotation is caused by many factors. In this paper, the characteristics of water supply network and the characteristics of the current water meter are analyzed, mainly for the following reasons:
Q:How can I distinguish water meters from dry ones?. Still wet?.
Magnetic element of dry water meterDry water meter magnetic materials are commonly used ferrite and NdFeB magnetic element, structure shape are generally annular columnar magnet, magnet and the annular magnet and the door shaped silicon steel sheet.
Q:What is the characteristic flow of a water meter?
Minimum flow: within the maximum allowable error limit, the minimum flow required by the meter is given. It is related to the value of the water meter code.
Q:What are the valves before the water meter and the water meter?
You said you want to install the water meter, the water meter or so, what kind of pipe fittings do you need? If it is the valve, it should be in front of the total water control valve, usually with copper ball valve, globe valve. The following can be arranged in accordance with the direction of the water pipe, where appropriate to use the valve, usually water mouth, galvanized, chrome like that. If it is installed water meter, it should be about the use of pipe fittings are live.
Q:The difference between electromagnetic flowmeter and electromagnetic water meter
In essence, it is a kind of instrument, the principle and structure should be the same. The electromagnetic flowmeter is produced according to the flowmeter standard, the error (accuracy level) is executed by flowmeter, and the accuracy is higher. The electromagnetic water meter is produced according to the water meter standard, and the error (accuracy level) is executed according to the water meter, and the accuracy is low. Do you have any questions?
Q:The new rotor type water meter, in dripping water, if the drip is very slow, for example, 10 minutes a drop, the water meter will turn? Do not know the reason, please do not answer, please explain the reason!
The new meter adds a cavity in the bottom case, and is connected with the water outlet, the middle with a soft diaphragm separated, and adding a valve at the outlet, when the outlet to drip out water, down to the deformation of soft membrane in the inlet pressure under the action when the water reaches a certain amount, drip proof device will open the outlet pressure, so as to drive the impeller to rotate to measure the effect process of water supplement is intermittent, measurement in the process of water leakage is intermittent. When the normal water valve, the sensor will follow the open, so that the water becomes a completely ordinary water meter.
Q:How do you connect the water meter with the PPR tube?
I do the installation, the general family water supply system, water meters are home, do not have to pick up their own water meters; Louzhu may be self-help construction it.
