In order to facilitate user operation and use, our company provides fully automatic measuring instruments to achieve accurate measurement of cold and heat.
This product has the characteristics of beautiful appearance, easy installation, accurate measurement, stable operation, strong anti pollution and anti-corrosion ability, long service life, small pressure loss, and economic practicality.
Applied in cold and heat metering facilities such as central heating, central air conditioning, and cold and hot combined supply.
Equipment Composition
This instrument mainly consists of paired temperature sensors, flow sensors, and integrators.
Pairing temperature sensors to measure the temperature of incoming and outgoing water;
The flow sensor measures parameters such as flow rate, instantaneous flow rate, and cumulative flow rate of cold and hot water flowing through the pipeline through time difference;
These two data points are collected and sent to the integrator, which calculates the amount of heat and cold used and displays it.
Integrator
The control center of the flowmeter receives and displays various data transmitted by flow sensors and temperature sensors, and calculates them. The Ogryan energy meter is an energy meter that integrates multiple functions, operation, and display,
Can be used for heating or cooling metering.
1. The protection level of the energy meter control box shall not be lower than IP56;
2. 7-inch touch screen display, real-time display of flow rate, instantaneous cooling/heating, supply water temperature, return water temperature and other parameters;
3. Equipped with remote communication, easy to operate and maintain.
