    BTU 100 L is a versatile compact energy totalizer extremely useful for measurement of energy conversion. It measures the thermal energy required for air conditioning. It accepts 3 inputs, each one from a flow meter for chilled water, inlet temperature sensor and the outlet temperature sensor. From this it calculates the thermal power and energy consumed in maintaining the temperature at given level. 9 digits are available for total energy and four digits are available for instantaneous power reading. The engg. Unit can be selected by user, either as KW & KWH Or BTU / Hr & BTU

    Advantages :

    • Compact Wall mounting design with IP 65 Enclosure.
    • 16x2 LCD for total energy as well as instantaneous power.
    • Display of chilled water flow, power temperature available.
    • Choice of mounting either on inlet or on outlet as per site conditions.
    • Choice of Engg. Units : KW or BTU.
    • Data storage up to 1 year with hourly storage facility with real time.
    • Storage can be viewed by scrolling keys.
    • Serial Interface with computer through MODBUS RTU.
