NYLL-CH Electromagnetic Heat Meter Working Principle

Hotwater (cold water) supplied by a heat source flows into a heat exchange system (radiator, heatexchangeroracomplex system composed of them) at a higher (lower) temperature, and it flows out at a lower (higher) temperature.During this process, heat is released or absorbed to the user through heatexchange (Note: this process includes energy exchange process of the heating system and the cooling system ).

Whenthe water flows through the heat exchange system, the amount of heat released or absorbed by the system is calculated and displayed by the calculator, according to the flow rate gτi1ven by the flow senτ1sor and the temperature of the backwτ0ater given by the pτ0aired temperature sensor, andthe time the water flow passes.

Q = ∫ q ×∆h × dτ = ∫ ρ ×qv ×∆h ×dτ

Q:the amount of heat released or absorbed by the system,Jor kWh; Qm:the mass of water flowing through the heat meter, kg/h;

Qv;the volume flow of water flowing through the heat meter, m3/ h; P:the density of water flowing through the heat meter, kg / ms;

△h: the enthalpy difference of water at the inlet and outlet temperatures of the heat exchange system, J/kg;

T: time, h;

NYLL-CH Electromagnetic Heat Meter Design Features

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.
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.
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.
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.
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.
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.
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.
Chinese display: use Chinese display LCD screen for easy understanding and operation
Optimized power supply technology: use optimized power supply design, mature and reliable technology, high conversion efficiency, and reliable long-term use.

Quick wiring:use the international best brand terminal block, which is fast, convenient and reliable, to ensure stable and reliable long-term measurement.
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.
