Transit-time Clamp-on - TUF333
The measuring principle of ultrasonic flow meter is based on ultrasound transmission through a liquid. Transit time measuring technique utilizes two transducers, which function as both ultrasonic transmitters and receivers. The ultrasound waves traveling in the direction of the flow of the liquid require less time than when traveling in the opposite direction. The subsequent time difference is directly proportional to the flow velocity in the pipe. Having measured the flow velocity and knowing the pipe cross-sectional area, the volumetric flow can be easily calculated.
• Non-invasive type measurement, no interruption to process and no risk of contamination
• It provides accurate measurement of liquid flowing within a closed pipe, without the need for any
mechanical parts to be inserted through the pipe wall or to protrude into the flow system.
• It takes just a few minutes to install and there is no need to shut down flow or drain the system
• With capabilities of measuring bi-directional flow and pipe diameter range from 13mm to 2000mm
• Water/wastewater
• Building Energy Management
• Semi Conductor Industry
• Pharmaceutical
• Petrochemical
• Food and beverage
