IIIElectromagnetic flowmeter with GPRS communication wireless transmissionNew features
lithium batteryElectromagnetic flowmeter is designed specifically for the water industry to ensure accurate water fee calculation for urban water supply. It is 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.
lithium batteryThe electromagnetic flowmeter adopts a specially designed sensor excitation system and intelligent system, and adopts a 16 bit embedded ultra low power consumption processor, full digital signal processing, stable operation, high measurement accuracy, strong anti-interference ability and other characteristics. It realizes automatic bidirectional flow measurement, on-site instantaneous flow, cumulative total amount display in both directions, self diagnostic 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 battery powered electromagnetic flowmeter integrates the instrument and control parts 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 buy water as soon as possible; When the user has no balance, the system automatically sends instructions to close the valve and cut off the pipeline.

This system can query, analyze, and display the water usage and pipeline pressure at each measurement point in the form of charts or curves, allowing users to easily manage the water usage at each measurement point.
When there is an abnormality in the water usage at the measurement point or when the battery level of the on-site flow meter is low, this system can issue an alarm message.
This system can set multiple operators at different levels to achieve hierarchical data management and enable data sharing within the user's local area network.
This system introduces more user-friendly management such as data backup and SIM card fee statistics.
