DN15-DN40 Photoelectric direct reading remote water meter

DN15-DN40 Photoelectric direct reading remote water meter

Thank you for purchasing the MW-LXSGY-15E~25E remote transmission series water meter. Please read this manual carefully before use to use the water meter correctly and effectively.

The MW-LXSGY direct reading remote water meter is used to measure the total volume of water flowing through the tap water pipe. The new water meter adopts new technology, and the design is novel and reasonable. The material selection is excellent, the appearance is beautiful, the assembly is precise, and the maintenance is convenient.

Features

1. The metering and other properties of this product have reached the national standard GB/T778.1~3—2007. And in line with the "electronic remote water meter" (CJ/T 224-2012)

2.The use of non-contact sensors does not affect the original performance of mechanical water meters.

3.The infrared radiation method is adopted to enhance the anti-interference ability; the non-mechanical contact mode does not cause the garbled phenomenon due to mechanical looseness.

4.With a low power design, power is only required for readings.

5.Special coding method, there is no dead zone of reading, the mechanical rotation and electronic reading can be kept when the character wheel is rotated to any position.

6. Using advanced data encoding and verification methods, communication reliability is high.

7. It can be combined with the meter reading system to establish a remote meter reading management system to truly realize meter reading automation.

8. The agreement is in line with the "Technical Conditions for Data Transmission of Household Meters" GJ/T188-2004 or MODBUS or both parties.

flow parameter

Conditions of use:

1. Water temperature: no more than 30 ° C; pressure: no more than 1 Mpa Working environment: Class B.

2. Upstream flow field sensitivity level: U10; downstream flow field sensitivity level: D5.

3. Transmission mode is divided into RS-485, MBUS bus transmission mode, working voltage: DC24V~42V (MBUS), DC12V±2V (RS-485)

4. Communication transmission rate: 2400bps (can be customized according to user requirements)

Nominal flow:

Allows long-term use of flow within specified tolerance limits.

indication error limit:

From the boundary flow (Q2) to the maximum flow (Q4) is ±2%, and the minimum flow (Q1) to the boundary flow (Q2) (excluding the boundary flow Q2) is ±5%.

Dimensions and weight:

Installation and maintenance methods:

1. Choosing the diameter of the water meter should be based on the size of the pipeline and the flow rate used.

2. The installation location should avoid exposure, freezing, pollution and flooding in order to disassemble and read the meter.

3. The water meter must be installed horizontally with the letter facing up and the direction of the arrow on the case in the same direction as the water flow.

4. Newly installed pipes must be flushed with stones, silt, hemp and other debris in the pipeline to refill the water meter to avoid water meter failure.

5. In order to measure correctly, the faucet should be higher than the water meter.

6. Maximum pressure loss: 0.063MPa

three bags:

1. Using our company's water meter within one year, if the installation is reasonable, the flow rate is normal, and the internal parts are damaged or malfunctioned due to the manufacturing quality (except for freezing). The company is responsible for repairing or replacing the lead when the lead seal is intact.

2. Any unit that uses our company's products for self-maintenance, such as water plants, industrial and mining enterprises, etc., our company provides repair parts, but must sign a contract with my sales department.
