Battery powered flowmeter

Introduction to battery powered electromagnetic flowmeter

Battery powered electromagnetic flowmeter is a specially designed measuring instrument for the actual requirements of water supply enterprises. It can optimize water supply and ensure accurate water trade measurement and settlement.

Compliant with ISO9104 (GB/T 18659) and ISO4064 (GB/T 778) standards, with precise measurement, high reliability, good stability, and long lifespan.

The battery powered electromagnetic flowmeter consists of two parts: an electromagnetic flow converter and an electromagnetic flow sensor.

Electromagnetic flow sensor: The main function of the sensor is to convert the flow signal into an electrical signal, which is composed of a measuring tube, electrodes, housing, etc.

Electromagnetic flow converter: The main function of the converter is to convert the electrical signal sent by the sensor into a digital signal after internal processing, thereby achieving flow measurement.

The battery powered electromagnetic flowmeter adopts a specially designed sensor excitation system, a high-performance lithium battery power supply system, and a 16 bit embedded ultra low power consumption processor, with the following functions:

1. Specially designed for the water industry to ensure accurate water fee calculation for urban water supply, widely used in industries such as urban water supply (cold water), urban heating (hot water), sewage treatment, and water conservancy engineering. Not affected by water quality interference, no entanglement or blockage, almost no pressure loss, and can work reliably and continuously for a long time. Especially suitable for high flow heating.

2. Adopting a specially designed sensor excitation system and intelligent system, and equipped with a 16 bit embedded ultra low power consumption processor, fully digital signal processing, stable operation, high measurement accuracy, strong anti-interference ability, etc., it realizes automatic bidirectional flow measurement, on-site instantaneous flow, cumulative total display in both directions, self diagnosis fault alarm, GSM/GPRS data wireless remote transmission and other functions. Users can achieve wireless remote transmission and storage of flow data through the powerful GSM/GPRS remote management software system. And it can automatically switch between multiple power sources of 3.6V/12V or 220V.

On the basis of precise measurement, the instrument and control parts are integrated to achieve automatic disconnection and connection of pipelines. The intelligent electric regulating valve operates slowly when opened, avoiding damage to the instrument caused by excessive liquid flow rate and preventing the occurrence of dangerous accidents. The opening of the valve requires users to pay in advance. When the user's balance is insufficient, the system will automatically send a text message to the user's phone, reminding them to recharge as soon as possible; When the user has no balance, the system automatically sends instructions to close the valve and cut off the pipeline. After the user recharges, the valve automatically opens and the pipeline is connected.

4. Electromagnetic flowmeter is the best choice for upgrading the measurement of large water users

Water is a precious and non renewable resource, and in today's era of promoting energy conservation and consumption reduction, it needs to be effectively measured and controlled. Accurate and fair measurement, effective supervision and control, are the basic means of conserving water and reducing waste. Implementing accurate and fair trade measurement, achieving large user measurement and monitoring, and implementing regional measurement methods to reduce leakage are the most direct ways for water supply enterprises to improve economic efficiency. The battery powered electromagnetic flowmeter provides a simple and most direct means to achieve the above objectives.

In pipeline water supply, more and more flow meters are being used for metering of large water users and regional metering systems to reduce leakage rates. To achieve leakage monitoring in the pipeline network, it is necessary to monitor the low water consumption at night.

It can provide high-precision measurement in both directions and is an ideal flowmeter for leak detection. Meanwhile, outstanding repeatability ensures that only true traffic mutations are detected.
