Xiamen JingchuanThe thermal oil flowmeter, when combined with the oil pipe temperature, can automatically calculate thermal energyCore technological advantages
Flow temperature linkage automatic calculation of thermal energyAdopting a dual parameter monitoring design of "flow measurement+temperature acquisition", the flow meter accurately measures the flow rate of thermal oil (range 0.5-100m ³/h), and at the same time, real-time collection of oil pipe inlet and outlet temperatures is achieved through built-in or external high-precision temperature sensors (measurement accuracy ± 0.3 ℃). Based on the thermal energy calculation formula Q=cm Δ T (where c is the specific heat capacity of the heat transfer oil, m is the mass flow rate, and Δ T is the temperature difference), the equipment can automatically convert the thermal energy value transferred by the heat transfer oil. The data update frequency can reach 1 second per time, without the need for manual secondary calculation, solving the problem of lagging thermal energy accounting caused by traditional "flow+temperature" separate monitoring.
High temperature adaptation for thermal oil working conditionsIn response to the long-term operation of thermal oil in a high temperature environment of 100-350 ℃, the contact medium components of the flowmeter are made of 316L stainless steel and high-temperature sealing material (with a temperature resistance of up to 400 ℃) to avoid component deformation or sealing failure caused by high temperature. The inner wall of the measuring tube is coated with a high-temperature wear-resistant layer to reduce the wear caused by long-term flushing of the heat transfer oil, while also reducing the residual adhesion of high-temperature oil, ensuring stable operation in high-temperature heating systems in industries such as chemical fiber and plastics, with an average time of over 12000 hours.
Dual parameter precise measurementFlow measurement adopts electromagnetic or volumetric measurement principles (optional), optimized for the high viscosity characteristics of heat transfer oil, with measurement error controlled within ± 0.5% and repeatability ≤ ± 0.2%. Even in the face of viscosity fluctuations caused by temperature changes in heat transfer oil, flow measurement stability can be maintained through dynamic compensation algorithms. The temperature collection uses a platinum resistance sensor (PT1000), which supports a measurement range of -50-400 ℃ and can capture real-time temperature difference changes at the inlet and outlet of the oil pipe, providing accurate temperature difference data for thermal energy calculation and ensuring that the thermal energy accounting error is ≤± 1%.
Intelligent data management and energy-saving analysisSupports 4-20mA analog signals and RS485 digital transmission (Modbus RTU protocol), seamlessly integrates with enterprise energy management platforms and equipment PLC systems, and uploads real-time core data of flow, temperature, and thermal energy. Built in large capacity data storage module (capable of storing 12 months of historical data), automatically generates daily/weekly/monthly thermal energy consumption reports, visually displaying the thermal energy utilization of different time periods and devices. When thermal energy consumption is abnormal (such as a sudden increase in energy consumption per unit product), the equipment automatically triggers an alarm to help management personnel quickly locate high consumption links, optimize heating processes, and reduce energy consumption costs.

How to calculate thermal energy and heat with a thermal oil flowmeter
Temperature difference method
Instantaneous value of thermal energy=mass flow rate x specific heat x (temperature 1- temperature 2)
The specific heat of heat transfer oil is 1.884 kJ/kg. ℃, which means that the thermal energy required to heat 1 kg of heat transfer oil up to 1 ℃ is 1.8884 kJ. Generally, liquids can only be calculated using the temperature difference method.
The specific heat of heat transfer oil is calculated based on the average of temperature one and temperature two.
The average specific heat of other liquids is set by the user themselves.
Example: The measured flow rate is 1.2t/h, the temperature difference between t1 and t2 is 30 ℃, and the specific heat is 1.884
The accumulated heat energy per hour is 67.98MJ
Enthalpy value method
Instantaneous value of thermal energy=K1 × mass flow rate × enthalpy value 1-K2 × mass flow rate × enthalpy value 2
This formula is only applicable to heat transfer oil, where enthalpy value 1 and enthalpy value 2 are obtained by checking the table based on temperature 1 and temperature 2, respectively. The enthalpy value of thermal oil can be set through parameters.
The instrument automatically accumulates the total thermal energy value based on the calculated instantaneous thermal energy value. When the reset permission in the thermal energy accumulation parameter group is set to "on", the thermal energy accumulation value can be cleared to the initial set value by pressing the key on the measured value digital display screen.
Specific heat method
Instantaneous value of thermal energy=mass flow rate x (K1 x specific heat 1 x temperature 1-K2 x specific heat 2 x temperature 2)
This formula is only applicable to heat transfer oil. The specific heat 1 of heat transfer oil is calculated based on temperature one, and the specific heat 2 is calculated based on temperature two.
