Transit time ultrasonic flow meter uses the time difference between the transit times of an ultrasonic signals generated by a pair of transducers that are mounted directly onto the pipe. It is suitable to measure bi-directional flow and liquid with low concentration of suspended solids.
The ultrasonic flow meter equipped with thermal energy module offers the capabilities to measure the rate and quantity of heat in British thermal units (BTU). The thermal energy module consists of 2 temperature sensors that measures the temperature difference between the supply and return lines.
Ultrasonic flow meter with thermal energy module is commonly used to measure the amount of energy generated and consumed in chilled and hot water for HVAC system (heating, ventilation, and air conditioning); or energy management system in commercial buildings.
Application Examples
- Chilled water systems for commercial, industrial and office buildings: The thermal energy modules are used to accurately bill users for air conditioning energy usage.
- Energy consumption of open heating/cooling systems: BTU can be used to optimize the performance of the system and to reduce energy consumption.
- Leakage detection in piping system: A sudden fluctuation in energy consumption of the system could indicate issues related to a leakage in the system.
- Peak load demand management and strategies: Peak load is the highest amount of energy that a consumer draws from the grid in a set period. Manufacturing industries usually have higher peak loads due to the usage of energy-intensive equipment. Operators can adjust start up schedules to reduce operating cost.
