Aug 26, 2009
Sierra Instruments has introduced the Innova-Sonic Model 205 thermal energy/BTU meter.
This transit-time ultrasonic flow meter is designed to measure the thermal energy flow rate and totalised energy consumption in liquid heating and cooling applications, including heating, ventilation and air conditioning (HVAC), office buildings, large condominium or apartment developments, solar thermal heating and geothermal heating.
The Model 205 thermal energy/BTU meter is designed to measure the thermal energy flow rate and total energy consumption in liquid heating and cooling applications
Non-intrusive clamp-on ultrasonic sensor technology facilitates installation.
The Model 205 thermal energy/BTU meter offers high accuracy (+/-0.5 per cent of reading), enabling the custody transfer of thermal energy.
Built-in totalisers and data loggers are used to record daily, monthly and yearly totalised energy usage and to report total energy used.
These functions help to account for energy usage and accurately allocate costs to end users.
A built-in SD card and a supplied data analysis and graphing program enable the storage and analysis of collected data.
The meter includes ultrasonic transducers, remote electronics and two PT100 resistance temperature detectors (RTDs) supplied by Sierra.
The two RTDs - either insertion or surface mounted - measure the temperature of the supply and return flow.
The meter's electronics then uses these inputs, along with the measured flow rate from the ultrasonic transducers, to calculate the thermal energy flow rate in user-defined units (BTU/hour or kJ/hour, for example).
The meter features an operating temperature range of -40F to +340F (-40C to +170C) and a bi-directional flow range of 0.0fps to 40fps liquids (0-12mps).
The instrument can be used for a range of pipe sizes from 1in to 200in (25mm to 5,000mm).
