Intelligent water meter/IC card water meter Battery

IC Card Water meter/intelligent water meter is an intelligent water meter products, at this stage has begun to promote the application of many pilots, because it is necessary to install the battery, to work, display data, so some users have produced such questions: if the IC card water meter/intelligent water meters is power off, will the water supply be cut off?

Multi Jet Water Meter     Prepaid water meter  

intelligent water meters need to recharge to buy a drink to use, after buying water on the meter inserted IC card, to water. However, in the use of the process, because of forgetting to replace the battery, many users found that the insertion of IC card, LCD screen has not shown the number, at this time will occur two kinds of possible problems, one is inserted card, water meter does not show the number, but the supply of normal tap. There will also be a situation, that is, immediately water. What are the reasons for these two different situations? This is because the IC card water meter/intelligent water meter motherboard battery and panel battery is different, if the LCD is not displayed, and will not affect the user normal water, at this time the user should replace the battery as soon as possible. And if the real water supply in the home, then there is almost only one reason, that is, intelligent meter monitoring to run out, automatic to the brake plate issued a signal.

If the home is out of water, and the water meter screen after the card does not show, there may be battery exhausted, can not work, you can replace the same type of battery. The following is a description of the replacement battery steps:
1, cut the battery compartment seal, remove the fixed cover of the screw, remove the battery. The battery compartment is on the bottom of the meter.

2, press the buckle, unplug the connector, disconnect the battery snap connection. Water meter used for two 3V lithium battery, model CR14505E two series, the battery and the water meter by the buckle connection.
3, the new battery to buy, pay attention to whether the positive and negative batteries with the original battery, mainly to see the connection line. If correct, plug the buckle with the water meter can be inserted.
5, at this time without worry on the battery cover cover, first with their own water card into the water meter, insert the water meter after the solenoid valve action, the screen shows the relevant figures, that the battery work properly, the water meter can work. Note: There may be a small amount of water in the water meter.

6, cover the battery cover, screw on the screw, if the water meter has been replaced, call the property staff to change the water meter on it

Characteristics and classification of volumetric water meter

1, an overview of positive displacement meter

Positive displacement water meters are installed in closed conduits, some being full and the successive emissions Chamber of known volume of fluid and with fluid-drive mechanism of a meter. Because with pistons rotating to record the amount of drinking water through the pipe, also known as piston water meters, with initial flow of small, high precision, hygiene, easy reading and so on. Especially suitable for high quality, high cost of water for the occasion. As volumetric water meter repair debug more complex and high requirements for quality reasons, not yet widespread use in our country.

2, volumetric water meter characteristic

⑴ LCD display, convenient and intuitive readings, and instantaneous flow rate display cumulative flow.

⑵ test mode displays the cumulative flow of higher resolution, small-diameter minimum resolution: 0.00001m 3.

C with the zero function, each time you enter the test mode, the cumulative flow of test mode is cleared to zero, more applicable industrial ingredients measure the water.

⑷ rotating piston structure, with a small initial flow rate, high measuring accuracy, wear-resistant, non-rotational inertia and so on.

⑸ can be horizontal, vertical, inclined installation does not affect the accurate measurement of water meters.

⑹ with antimagnetic interference function, pleasing in appearance, small size, light weight and so on.
Volumetric (Piston) Type Water Meter

3, positive displacement meter classifications

Rotary piston volumetric water meter type and disc type, the two series, when the water flow through the meter, and water-driven piston (disc) rotation (Swing), and piston-cylinder (disk) the volume is constant, so the piston rotation measured by counting bodies (disc swing) number can be informed of water flow through the meter.

The main products for rotary piston volumetric water meter water meter, disc-type water meter did not use abroad for only the United States and a few other countries. Rotary piston meters for small caliber specifications, is characterized by high level of measurement (up to level c and level d) ability, high sensitivity, low flow rate measurement. Primarily used for metering of pipeline pure water in China, Ningbo Guoxin instrument technology limited, water meter products represented, meter size typically 8, 15, and 20mm.

Processing method of Rotary Volumetric Piston Water Meter installation techniques, characteristics, operation process, working principle and common problems

Volumetric meter is also called the piston type water meter, is a constant flow type water meter. The national standard in the volumetric meter is defined as “installed in the closed pipe, by some to be a water meter chamber volume successive full known and discharge fluid and with fluid driven mechanism.

Rotary Volumetric Piston Water Meter

Volumetric meter with rotary piston type and disc type two series, when the water flow through the meter, the drive piston flow (circleRotating disc) (swing), and a piston cylinder (disk chamber) volume is constant, so, by counting the measured piston rotation mechanism

Turn (disc swing) times, can get through the Rotary Volumetric Piston Water Meter of water.

Product volume type water meter is the main rotary piston type water meter, see figure C.5 and figure C.6 appendix C. At present is mainly used for the measurement of pipeline pure water, water purification water to produce drinking water meter water Limited by Share Ltd Ningbo and Ningbo Donghai instrument channel limited company as the representative, in the water meter diameter is 8, 15 and 20ram. Volumetric meter repair debugging complex, high requirement on quality, used in China has not yet been widely. Under the action of water pressure, water from the lower water inlet into the measurement chamber, center 3 driven rotary piston 7 surround the measurement chamber shaft to rotate, and the water from the piston blank and piston and the measuring chamber wall surface formed by the air flows to the upper outlet, at the same time the piston rotates, connected by a rotating shaft 4 and shifting fork 5 and counting mechanism, so as long as the note of piston rotation times, can flow through the water volume. Under the action of water pressure, water from the lower water inlet into the measurement chamber, center 3 driven rotary piston 7 surround the measurement chamber shaft to rotate, and the water from the piston blank and piston and the measuring chamber wall surface formed by the air flows to the upper outlet, at the same time the piston rotates, connected by a rotating shaft 4 and shifting fork 5 and counting mechanism, so as long as the note of piston rotation times, can flow through the water volume.

Volumetric meter with rotary piston type and Yuan Pan type two series, its principle is, when the water flow through the meter. The drive piston flow (Yuan Pan) rotation (swing), and the piston cylinder (Yuan Pan chambers) volume is constant, so, by counting mechanism measured piston rotation (Yuan Pan wobble) number it can obtain the flow through the water, water meter.

Requirements of installation and operation:

Requirements of installation and operation:

A, flow direction must be with the table on the arrow direction; B, the installation position to avoid pollution and flooding

This table for the Rotary Volumetric Piston Type Plastic Water Meter, the piston principle, through the rotation of the piston to measure the amount of water through the pipe.

Housing for the pressure casting of brass or stainless steel precision casting, internal main parts use of carbon composite materials, the counter is fully enclosed structure, flow into a eight bit digital recording.

Measurement grade this table for the C class, high sensitivity, small starting flow, clear reading, easy to install, without any range limit.

Measurement of the surface is most suitable for direct drinking water.
