Overview
The Intelligent electromagnetic BTU meter is a type of measuring instruments,which measure the heat-carrying fluid heat exchange.Using Faraday electromagnetic induction principle of electromagnetic flow measurement technology with high precision high reliability to measure flow,using platinum thermal resistance with high precision high stability to measure temperature,and using the powerful embedded processor for flow and temperature collection and calculation.It is based on above means,according to the thermodynamics formula to calculate the heat transfer fluid release quantity of heat.Features
- Empty pipe detection:using intelligent fuzzy technology for empty pipe detection with High safely and reliability,and calibration can be used unnecessary
- The current output is designed of LSI chip,the output is stability,reliability,interoperability,no need current zero correction and current full-scale correction
- Measurement the damping using wavelet transform algorithm,it can guarantee the stability of flow measurement,but also ensures that the real-time response to flow changes
- Using LCD module with wide temperature range,the LCD backlight with auto-off function to Extend the service life of the LCD,the LCD state is monitoring by real-time to ensure that the LCD reliable operation
- The Intelligent temperature measurement circuit and algorithm is designed to solve the impact of ambient temperature for the device and ensure the meter operation on Long-term stability
- The analog signals,digital signals,and output signals are fully isolated.The Input interface,output interface and power port are using anti overvoltage,lightning and surge protection design,to ensure the anti-interference ability
- It can measure the forward flow and backward flow.There are three internal totalizers,it can display including forward cumulative flow,backward cumulative flow rate and the difference cumulative flow.It can be switch control the output of backward measurement.It also can output flow direction indicator signal
- Heat measuring and displaying,supply water and return water temperature and temperature difference measuring and displaying
- With the Modbus protocol communication interface (RS485) and Profibus protocol communication interface,it is easy to quick connect with the PLC or control devices
