Electromagnetic flowmeter battery power

Overview

Working principe of Electromagnetic flowmeter battery power
The Electromagnetic flowmeter battery power is made by using Faraday's law of electromagnetic induction. When the conductive liquid moves along the measuring tube in an alternating magnetic field perpendicular to the magnetic line of force, the conductive liquid cuts the magnetic line of force and generates an induced potential. A pair of electrodes are installed on the tube wall perpendicular to the axis of the measuring tube and the magnetic line of force, which detects the generated induced potential. The induced potential is directly proportional to the flow, and the flow through the sensor can be derived by measuring the induced potential. As shown in figure (4.1). The flow signal (induced potential) input converter is amplified and converted into a digital signal proportional to the flow signal, so as to realize flow measurement.

Product features of Electromagnetic flowmeter battery power

1. It is specially designed for water industry to meet urban water supply and ensure accurate water charge calculation. It is widely used in urban water supply (cold water), urban heating (hot water), sewage treatment, hydraulic engineering and other industries. It is free from water quality interference, winding and blockage, almost no pressure loss, and can work reliably and continuously for a long time. It is especially suitable for large flow heating.
2. The specially designed sensor excitation system and intelligent system are adopted, and the 16 bit embedded ultra-fine power consumption processor, full digital signal processing, stable operation, high measurement accuracy and strong anti-interference ability are adopted to realize the functions of automatic two-way flow measurement, on-site instantaneous flow, positive and negative cumulative total amount display, self diagnosis fault alarm, GSM / GPRS data wireless remote transmission, etc, Users can realize the functions of wireless remote transmission and storage of traffic data through the powerful GSM / GPRS Remote management software system. It can realize the automatic switching of 3.6v/12v or 220V multi-channel power supply.
3. On the basis of accurate measurement, the instrument and control parts are integrated to realize the automatic cut-off and connection of the pipeline. The intelligent electric regulating valve acts slowly when opening, which avoids the damage to the instrument itself caused by the excessive liquid flow rate and prevents the occurrence of dangerous accidents. The opening of the valve requires the user to pay in advance. When the user's balance is insufficient, the system will automatically send a short message to the user's mobile phone to prompt the user to recharge as soon as possible; When the user has no balance, the system will automatically send instructions to close the valve and cut off the pipeline. After the user recharges, the valve will open automatically and connect the pipeline.
4. Electromagnetic flowmeter is the best choice for measurement upgrading of large water users
Water is a precious and non renewable resource. Today, when energy conservation and consumption reduction are advocated, it needs to be effectively measured and controlled. Accurate and fair measurement, effective supervision and control are the basic means to save water and reduce waste. The most direct way for water supply enterprises to improve economic benefits is to implement accurate and fair trade measurement, realize large user measurement and monitoring, and implement regional measurement methods to reduce leakage. Battery powered electromagnetic flowmeter provides a simple and direct means to achieve the above purpose.

In pipe network water supply, more and more flow meters are used in large water user metering and regional metering systems to reduce the leakage rate. To realize the monitoring of leakage consumption in the pipe network, it is necessary to monitor the night with low water consumption.
It can provide two-way high-precision measurement and is an ideal flowmeter for leakage detection. At the same time, excellent repeatability ensures that only real traffic mutations can be detected.
