Direct reading electromagnetic water meterIt is a flow measurement instrument designed based on Faraday's law of electromagnetic induction, specifically designed for water supply, drainage and other water related scenarios. Its core advantage lies in directly reading flow data without the need for complex signal conversion or secondary calculations. Combined with the high-precision characteristics of electromagnetic measurement technology, it has demonstrated significant advantages in fields such as municipal water supply, industrial water use, and agricultural irrigation. Here are its core advantages:

1. High measurement accuracy and strong stability

Principle advantage: Based on the principle of electromagnetic induction, flow measurement is only related to flow velocity and magnetic field strength, and is not affected by physical parameters such as fluid density, viscosity, temperature, and pressure, ensuring long-term measurement stability.

Accuracy level: usually reaching 0.5 or higher, far superior to mechanical water meters (1.5-2.5 levels) and some ultrasonic water meters (1.0 level), especially suitable for scenarios with strict accuracy requirements such as trade settlement and water resource management.

Anti interference capability: No mechanical moving parts, avoiding accuracy degradation caused by wear and blockage, and insensitive to pipeline vibration and electromagnetic interference, with high data reliability.

2. Direct reading design, simplifying operation and maintenance

Data direct display: By using a built-in microprocessor to directly calculate and display parameters such as instantaneous flow rate and cumulative flow rate, without the need for external converters or complex calculations, operators can quickly read data.

Low maintenance requirements: No mechanical transmission components, reducing failures caused by wear and jamming, and the maintenance cycle can be extended to more than 5 years, reducing the total lifecycle cost.

Self diagnostic function: Some models have intelligent diagnostic functions such as air traffic control detection and electrode contamination alarm, which can warn potential problems in advance and reduce the risk of shutdown.

3. Wide range ratio, suitable for complex working conditions

Large dynamic range: The range ratio can reach 1:200 or even higher (traditional water meters usually have a ratio of 1:50-1:100), which can simultaneously meet the needs of small flow leakage monitoring (such as minimum flow at night) and large flow water metering.

Low flow velocity measurement: The minimum flow velocity can be as low as 0.01m/s, effectively capturing small flow changes and assisting in leakage control. According to statistics, it can reduce pipeline leakage rates by 10% -30%.

High flow rate compatibility: The maximum flow rate supports 5-15m/s (depending on the diameter), suitable for high flow scenarios such as industrial water and fire water.

4. Easy installation and strong adaptability

Low requirements for straight pipe sections: only the first 3 times the pipe diameter and the last 1 time the pipe diameter are needed (traditional mechanical water meters require 5-10 times the first and 2-5 times the last), reducing installation space requirements, especially suitable for the renovation of old pipe networks.

Bidirectional measurement: automatically identifies fluid direction, supports forward and reverse flow measurement, suitable for bidirectional flow scenarios such as circulating water systems and pump stations.

Multi caliber coverage: The caliber range is DN15-DN3000, which can match the full scenario demand from residential water to large-scale industrial water supply.

5. Data integration and intelligent management

Multi interface support: equipped with communication modules such as RS485, M-Bus, LoRa, NB IoT, etc., it can seamlessly integrate into the smart water platform to achieve remote meter reading, data analysis, abnormal alarm and other functions.

Battery powered options: Some models adopt low-power design, with built-in lithium batteries that can work continuously for 6-10 years without the need for external power supply, reducing deployment costs.

Data Security: Supports encrypted transmission and storage, complies with information security standards such as ISO/IEC 27001, and prevents data tampering or leakage.

6. Environmental Protection and Economy

No pressure loss design: There are no obstruction components in the flow channel, and the pressure loss is extremely small (usually ≤ 0.01MPa), reducing the energy consumption of the pump station and in line with the concept of green water supply.

Long life cost: Although the unit price is higher than mechanical water meters, due to maintenance free and long lifespan (more than 10 years), the full life cycle cost is lower, and the return on investment is significant.

Application scenario examples

Municipal water supply: used for water metering in residential areas and commercial complexes, supporting the implementation of tiered water pricing.

Industrial water usage: Monitor the cooling water and process water usage of chemical, steel, and other enterprises to optimize production processes.

Agricultural irrigation: Accurately measuring the amount of irrigation water in farmland to support the development of water-saving agriculture.

Leakage control: By analyzing the minimum flow rate at night, locate the leakage points in the pipeline network and reduce water resource waste.
