Products Description
The intelligent electromagnetic energy meter (electromagnetic heat and cooling meter) consists of a flow measurement unit, a heat calculation unit and a paired temperature sensor (PT1000).
The flow meter uses the Faraday electromagnetic induction principle to measure flow, and combined with the supply and return water temperature signals of the paired temperature sensor, it can calculate, accumulate, store and display the cold heat absorbed or released in the heat exchange loop.
The flow meter’s flow and energy calculation unit CPU and sampling module all adopt internationally advanced microcontrollers, which have large memory capacity and high equipment reliability. The heat calculation can truly realize consistent value calculation and achieve high accuracy. The complete set of matched temperature sensors uses platinum resistor Pt1000, and its matching error is ≤0.1℃
Paired temperature sensors (a pair of Pt1000 platinum resistance temperature sensors) are installed on the inlet and outlet pipes of the heat exchange circuit of the air conditioning or heating system to accurately collect the temperature values of the supply and return pipes and transmit signals.
Install the flow sensor (pipeline electromagnetic flowmeter) on the inlet or outlet pipe to accurately collect and calculate the flow value of the pipe network and transmit the signal.
The energy calculator is used to receive temperature and flow signals and calculate and store energy consumption. The effective data in the energy calculator (such as accumulated heat value, cooling capacity value, equivalent flow value, supply and return water temperature and temperature difference) is transmitted to the computer to realize intelligent management.
