iSOLV BTU Measurement


iSOLV BTU Measurement System is used to measure individual energy consumption in any liquid heating/cooling systems. This system is also used to measure performance of energy saving system or the loss of efficiency which is directly tied to loss of revenue.

The iSOLV BTU Measurement System is supplied complete with electromagnetic flowmeter and temperature probes. The system real-time detects the temperature of supply and return pipe. It also monitors the instantaneous flow rate according to Heat Exchange of Thermodynamics principle. The iSOLV BTU meter automatically integrates energy consumption and transfers it to the computer. The consumption volume can be checked by a tenant or operator with no worries. It provides real time information such as instantaneous temperature, flow rate, energy consumption, and others.

Features

• Complies with OIML R75 and EN1434 standards.
• Real time display of supply / return water temperature, instantaneous flow rate, cooling consumption value, heating consumption value, instantaneous power, total flow rate etc.
• Four different units of measurements available: MJ, GJ, kWh/h, MWh/h
• Password protection available.
• RS485 Communication protocol.
• Matched pair of 3-wire Temperature sensor PT1000, for higher resolution and better accuracy

Application

• BTU meters measure the energy content of liquid flow in British thermal units (BTU), a basic measure of thermal energy.
• BTU meters are used in chilled water systems for both commercial and industrial and office buildings. These meters are used to bill users for energy usage.
