(1) overload flow (Q4) - the maximum flow allowed to run over a short time beyond the rated flow. Under this flow, the water representation value error is in the maximum allowable error, when the recovery is under the rated working conditions, the meter characteristics of the meter are unchanged.
(2) minimum flow rate (Q1) - the minimum flow rate for the water table rated flow rate, which is the maximum permissible error in this flow.
(3) boundary flow (Q2) - between the usual flow Q3 and the minimum flow Q1, the flow of water meter is divided into high and low zone flow. High and low regions have corresponding maximum permissible errors.
(4) common flow (Q3) - maximum flow under rated working conditions. Under this flow, the water meter works normally and the value error is within the maximum allowable error.
2. Indication error:
(1) from the minimum flow to the low zone that does not include the boundary flow: plus or minus 5%
(2) from including boundary flow to high areas including overload flow: plus or minus 2%
3, using temperature: 0 ~ 30 ºC
4. Nominal pressure: no less than 1.0mpa
5. Pressure loss: no more than 0.063 MPa

4. Installation and maintenance methods
Select the water meter according to the pipe diameter and flow size of the installation site.
2. The installation location should avoid exposure to the sun, water, freezing and pollution. In rainy season and winter, anti-rain anti-freezing measures should be taken.
3. Remove the hemp and gravel in the pipeline before installation, so as not to cause water meter failure.
4. When installing, valve should be installed in front of the meter in order to cut off the water table.
5. The LXS type water meter should be installed horizontally and the dial should be in the direction of the direction of the direction of the flow direction.
6. Water meter, if installed in the boiler, should prevent hot water from returning to the hot water meter (see picture below).
V. complete set
Attach the pipe joint, connecting nut and seal gasket to each of the water meter, using the instruction manual and the certificate each.
Six, services,
1, the use of our water meter a year, every reasonable install, use the traffic is normal, is the interior damage or malfunction caused by manufacturing quality (with the exception of freezing), and in keeping the seal under the condition of complete, the factory can be responsible for the repair, exchange, and pay for round trip (mail).
2, who use our products to repair units, such as water plant, industrial and mining enterprises, etc., our factory supply repair parts, but must sign a contract with our factory sales department, the contract and parts atlas on application to our factory.

Company Introduction:
Zibo Haiyuan Intelligent Meter Co., Ltd is established in Zichuan tap water company water meter factory and Zichuan District Station on the restructuring of the modern enterprise. Company R & D, sales, service in one, the market as the guide, to scientific and technological innovation, science and technology enterprises as the theme of development. Our company is specializing in the production of water meter enterprises, mainly the production of 15-25mm contactless IC card water meter, 15-25mm contact type IC card water meter, LXLY15-25 intelligent direct reading water meter, LXLGD- (50-200) mm wireless remote meter large aperture and intelligent direct reading gas meter (with valve controlled), LXS15-50 series rotary wing wet water meter and LXL80-200 spiral wet water meter and LXLC50-200 type series of detachable spiral dry water meter. My company has strong technical strength, and has advanced water meter production, calibration and flow testing equipment, strong technical force. The company spirit of "quality, customer first" business principles, strengthen quality management, respectively in 2002 and 2004 two by the State Administration of Quality Supervision Inspection and Quarantine of the national product quality supervision and inspection (inspection report No. 200217-011 and 200406-28 in stream flow).
