Alsonic Building Automation - Energy meters employ transit-time ultrasonic flow measuring technology combined with two integrated PT1000 RTD temperature sensors for calculating both total and instantaneous energy consumption. These in-line ultrasonic flow meters are available for line sizes ranging from ½" to 4" (15-100mm). The Alsonic BA Energy meter may be used to provide highly accurate thermal energy measurement in chilled water, hot water and condenser water systems. Our battery powered, microprocessor-based field programmable electronics provide local indication of energy, flow and temperature data via an alphanumeric LCD display. An isolated solid state dry contact is provided for indication of pre-programmed totals or alarm conditions. Optional analog outputs and RS485, M-bus as well as other network communications are also available.
