Features
â– Measurement of cold and heat: the converter has the function of measuring cold and heat directly, and equiped with 2 standard Pt1000. It does not need to be equipped with a cold and heat flow totalizer to facilitate installation and reduce the cost of purchasing and installation.
â– High reliability: After rigorous tests such as EMC, safety, high and low temperature, which are higher than national standards GB/T17616, G B/2423, GB/T16499.
â– Fast response: Use 32BitMCU, 24BitADC and optimized filtering algorithm, fast response, accurate and stable measurement data, suitable for measurement and control when equipment is matched.
â– Grounding electrode: NONCON patented technology, which forms measurement balance in measuring section and eliminates measurement error caused by poor grounding to ensure long-term measurement accuracy. It does not need to be equipped with a grounding ring to reduce material and installation costs.
â– Separate IP68 technology: use specially detailed IP68 design technology, use special imported IP68 sealant, special IP68 cable and multiple IP68 seal design to prevent the condensation of the separate IP68 sensor.
â– High signal-to-noise ratio: the sensor uses high signal-to-noise ratio technology. The converter uses low-noise and high-precision parts and design technology to facilitate measurement of minimum flow.
â– Low-power design; optimized excitation circuit design, power consumption is reduced by more than 3 times compared with conventional electromagnetic flowmeters, and it can achieve energy saving in a large number of applications.
â– Chinese display: use Chinese display LCD screen for easy understanding and operation
â– Optimized power supply technology: use optimized power supply design, mature and reliable technology, high conversion efficiency, and reliable long-term use.
â– Quick wiring:use the international best brand terminal block, which is fast, convenient and reliable, to ensure stable and reliable long-term measurement.
â– Output signal: epuiped with standard RS-485, (4-20) mA, frequency / pulse, fast output response, and the port is provided with protection measures such as lightning protection.

Installation Requirements
1. The pipe must be cleaned before the heat meter installation.
2. The heat meter is a precision meter, it must be careful when installing, and it is forbidden to lift the meter head and sensor wire; it is forbidden to squeeze the temperature sensor to prevent damage to the meter;
3. The direction indicated by the arrow of the heat meter sensor body indicates the direction of water flow, and theoretically, it is not allowed to reverse;
4. The front end of the heat meter pipe must be equipped with a filter of the corresponding diameter;
5. When installing the heat meter flow sensor, it shall ensure that there is at least 10 pipe diameter straight pipe sections upstream of the heat flow direction of the heat meter pipe, and at least 5 pipe diameter straight pipe sections downstream of the heat meter pipe;
6. The two ends of the heat meter must be equipped with the corresponding diameter valve, which can be separated from the heat meter for the cleaning and maintenance of the heat meter during use;
