Transducer Selection for Ultrasonic Transit-Time Flow Measurement Chambers: The Working Conditions Decide Everything![Dayu Electronics]

　　Customers often ask how to select the right ultrasonic transit-time flow measurement chamber transducer.

　　Different working conditions require different transducers, depending on the specific application.

　　Below, let's first take a look at what a transit-time flow measurement chamber looks like.

　　Ultrasonic transit-time flow measurement chamber

　　Water quality: standard water quality. The water contains no solid particles, with up to 0.1% powdered solids.

　　Water flow velocity range: minimum 0.2 m/s, maximum 10.0 m/s.

　　The transducers for the transit-time flow measurement chamber fall into the following two categories:

　　Note: The following transducer selections are conventional choices and do not take into account the developer's circuit design level or software algorithm capabilities.

　　Category 1:

　　Used on a transit-time flow measurement chamber with a maximum width of 1.5 meters. This range is relatively low, and a small, relatively high-frequency transducer can be selected, such as:

　　Transducer frequency: 1 MHz.

　　Model: KDYW-1M-01U-CTY;

　　Category 2:

　　Used on a transit-time flow measurement chamber with a maximum width of 1.5 meters.

　　The water contains up to 1% granular solids or up to 5% powdered solids. This working condition requires a transducer with a relatively high frequency and stronger penetration, such as:

　　Transducer frequency: 500 kHz.

　　Model: KDYW-500-05DA-CTY;
