DN20 0.05-5m³/h Ultrasonic Heat Meter for Integrated Heating Central Air Conditioning Metering

Description:
An ultrasonic heat meter is a smart meter consisting of a temperature sensor, a flow sensor and a calculator. The calculator enables accurate metering of flow, heat or cooling by processing the temperature difference collected by the sensor and the time difference between the sound waves passing through the fluid. In addition, it provides documentation and data transmission for various applications in heating or cooling pipelines.

The ultrasonic heat meter uses ultrasonic flow technology to measure flow by using the influence of water flow on ultrasonic propagation. Free from impurities in water and strong magnetic interference, its measurement is more stable and accurate. It supports both horizontal and vertical mounting, guaranteeing accurate metering. It can meet the needs of cooling capacity measurement of water-cooled central air conditioning.

It is suitable for energy metering and charging projects such as central heating, central air conditioning and combined heating and cooling.

Features:
- Ultrasonic heat meter with high reliability, wide measurement range and strong anti-interference ability. It is convenient, fast and economical to measure heat.
- Detect real-time flow and achieve accurate metering.
- Good protection performance: IP65 protection level. When there is spraying water, water does not enter the housing of the meter. So it can be immersed in water for a short time.
- High strength and pressure resistance: made of imported engineering plastics, its shell strength is high.
- Hot and cold measurement: After high and low temperature, its shell does not deform, and the measurement remains unchanged.
- HD backlit LCD display: It is convenient and intuitive to read meter (heat, cooling, instantaneous flow, cumulative flow value, etc.).
- All copper pipe section: The pipe section adopts international standard all-copper pipe section, which is anti-corrosion and moisture-proof, with long-term stability.
- Automatic SMT: Circuit using SMT (surface mounted technology) guarantees high-quality product performance and extremely low maintenance rates.
- RS485 interface: Infrared/RS485 communication output to realize data remote transmission and centralized control.
- Applicable fields: Widely used in residential areas, shopping malls, rental houses, schools, etc. It can be used as a metering instrument for cooling capacity, heat, flow, temperature difference and the like. It is an essential meter for heating metering.

Functions:
- Class 2 and class 3 of classification verification can be carried out according to user requirements.
- The flow meter channel is not easy to block and basically no pressure loss, which ensures the smooth circulation of the heating pipe and the heating efficiency.
- Inlet, return water, vertical and horizontal installation. Easy to use and maintain, with dustproof, moisture-proof, anti-disassembly, anti-strong magnetic attack and other functions.
- Imported transducer, ultrasonic flow chip GP2 and no mechanical rotating parts. Not easy to damage. Simple maintenance and prolonged service life.
