Ultrasonic flowmeters are a variety of flow meter of which measures the velocity of an fluid with ultrasound to help calculate volume movement. Ultrasonic flowmeters are affected by the acoustic properties with the fluid and might be impacted by temp, density, viscosity and suspended particulates based on the exact flow meter. They vary greatly in final cost but are often inexpensive to make use of and maintain because they don’t use moving elements, unlike mechanical movement meters. There are three different types of Ultrasonic flowmeters: Transmission flowmeters, Reflection or Doppler flow meters and Open-Channel flowmeter.
