Energy Flow Meters

Energy Flow Meters

Energy Flow Meters Overview: Flowmeters that perform energy measurement consist of a flowmeter with integrated temperature measurement to measure both supply and return temperature and then calculate thermal energy in units of BTUs. In addition to providing direct BTU measurement, these flowmeters also can display liquid flow rate and process temperature. The temperature measurement is typically achieved via use of precision RTD elements while the liquid flow rate measurement can be done with an electromagnetic flowmeter, a turbine flowmeter, an ultrasonic flowmeter, or a variety of other flowmeter technologies.

SmartMeasurementTM offers Energy flow meters that employ ultrasonic and magnetic flow measurement technologies in order to provide users with a degree of flexibility in selecting the best product for their specific application.  For non-intrusive energy measurement, the ALSONIC-EG provides highly accurate energy measurement for applications including treated water with low electrical conductivity and buildings where the air-conditioning can’t be turned off to install the meter.  The ALSONIC-EG enables retrofitting of transducers under pressure with a clamp-on non-intrusive installation method. For applications where there are particulates or bubbles entrained in the fluid, the ALMAG-EG, which makes use of a Mag Meter to measure the liquid flow, is the instrument of choice.  All SmartMeasurement BTU Flowmeters are available with optional Mbus, BACNET, MODBUS, and Profibus communication protocols.
