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 style flow sensors are available for line sizes ranging from ½" to 12". 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 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-programed totals or alarm conditions. Optional analog outputs and network communications are also available.
