What Is A Non-Magnetic Inductive Water Meter?
A non-magnetic inductive 수도 계량기, also known as an induction water meter, is a type of meter that uses a non-magnetic component for signal transmission to record water consumption. This design reduces interference from external magnetic fields.
How Does An Inductive Water Meter Work?
This type of inductive sensor water meter operates on the principle of the Hall effect to transmit water usage data.
Specifically, the meter sends signals through the rotation of a signaling pointer on its dial. Each time this signaling pointer completes one full rotation, a Hall effect sensor executes a switching action. This records the number of rotations. By multiplying the number of rotations by the volume of water corresponding to a single rotation, the total water consumption can be accurately calculated.
Finally, using remote communication protocols such as LoRa, NB-IoT, or M-Bus, the non-magnet inductive water meter can achieve remote data transmission.
Note: The signaling pointer is the semi-circular metal piece attached to the pointer of the lowest reading unit on the water meter’s dial.
Can The Signaling Frequency Of Inductive Meters Be Customized?
Yes. BMAG can customize the signal transmission frequency according to customer requirements. For example, it can be set to send a signal for every 0.0001m³, 0.001m³, 0.01m³, or 0.1m³, or the meter can be designed to signal once per 1 liter, 10 liters, or 100 liters.
The method is simple: by installing the metal signaling piece on pointers representing different units of measurement, the signaling frequency can be changed. This allows for flexible adjustment of both metering precision and the energy consumption of the signaling device.
What Is The Difference Between Non-Magnetic Inductive Water Meter And Magnetic Inductive 수도 계량기?
Traditional sensing water meters use magnetic material for the signaling pointer. While magnetic materials are generally more sensitive to the Hall effect, they have poor anti-magnetic performance. BMAG has updated its products to use non-magnetic materials, providing a more significant advantage in preventing water theft.
What Are The Advantages Of A Non-Magnet Inductive Water Meter?
Early sensor-equipped water meters all used magnets as the sensing element. However, magnets are highly susceptible to external magnetic fields. When a strong magnetic field is nearby, the magnetic pointer can slow down or even stop rotating, causing the meter to under-register or stop measuring altogether. With the advancement of magnet technology, high-performance magnets like NdFeB have become widely available at low costs. Many users maliciously attach strong magnets to their water meters to stop the measurement, thereby stealing water and causing significant financial losses for water utility companies.
By using non-magnetic materials, the induction water meter fundamentally eliminates the possibility of interference from external magnetic fields, effectively preventing property losses for water utilities caused by theft.
What Are The Application For No-Magnet Inductive Water Meter?
The inductive meter is ideally suited for residential use. Statistically, residential users account for the highest percentage of water theft incidents, making them the most suitable candidates for installing non-magnetic meters.
Industrial water meters should also be non-magnet inductive water meters. Water consumption in the manufacturing sector is enormous, with some factories using nearly as much water as 1,000 households. If theft occurs on an industrial scale, it can also lead to massive uncollectible water bills.
How to Install and Maintain an Inductive Meter?
The installation method for a non-magnetic sensor water meter is the same as for a standard water meter. Key points to note are:
- Pay attention to the installation direction, ensuring the arrow on the meter body aligns with the water flow direction.
- Ensure the pipeline is clear and free of contaminants.
- Avoid inclined installation to prevent measurement inaccuracies.
- The electronic components for remote transmission are mostly made of plastic and should be protected from prolonged sun exposure and freezing temperatures.
Inductive Water Meter Cost-Effectiveness
The purchase cost of a non-magnetic sensor water meter is almost the same as a magnetic one. However, preventing losses from water theft effectively increases revenue for the utility company.
Models with remote transmission have a higher initial purchase cost than those without this function. However, they significantly save on the long-term expenses of manual, on-site meter reading, offering greater cost-effectiveness over time.
Which Non-Magnetic Sensor Water Meter Is Better?
BMAG‘s water meters have undergone multiple revisions and updates. They are made with high-quality, non-magnetic materials and have been repeatedly tested to completely avoid interference from external magnetic fields, achieving a truly anti-magnetic design that protects the assets of water utility companies. It is one of the most trustworthy water meter products available.
