What is an ultrasonic flow meter?An ultrasonic flow meter measures the flow rate of a fluid using ultrasound waves. It calculates the flow based on the time difference or frequency shift of the ultrasonic signal. What are the two main types of ultrasonic flow meters? Transit Time (Time-of-Flight) Doppler Type...
1. What is a vortex flow meter? A vortex flow meter measures the flow rate by detecting the vortices shed from a bluff body placed in the flow stream. It uses the Von Kármán effect. 2. What is the principle behind vortex flow meters? Vortex flow meters operate on the...
1. What is the working principle of a Coriolis mass flow meter? Answer:It works on the Coriolis Effect, where a vibrating tube carrying fluid experiences a phase shift or twist proportional to the mass flow rate. The fluid’s inertia causes this deflection. 2. What type of flow does a Coriolis...
✅ Basic Conceptual Questions What is a turbine flow meter and how does it work?A turbine flow meter measures volumetric flow rate using the mechanical motion of a rotor placed in the flow stream. The fluid flow turns the rotor; the rotational speed is proportional to flow rate. What is...
