Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...
The technique is inherently self-cleaning. It is highly recommended for liquid level measurement applications where ultrasonic, float or microwave techniques have proved undependable. The system will require constant supply of air during measurement. The end of the tube should be above certain height to avoid sludge from clogging the tube.
A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
Ultrasonic sensors use two techniques to detect bubbles, one method involves transmitting sound waves from a transducer through the fluid to a second transducer that detects the waves. A second method involves pulse-echo, sound waves are transmitted to the fluid, reflected and received by the same transmitter that sent it. In both of these ...
Ultrasonic water meters use one or more ultrasonic transducer to send ultrasonic sound waves through the fluid to determine the velocity of the water. Since the cross-sectional area of the meter body is a fixed and known value, when the velocity of water is detected, the volume of water passing through the meter can be calculated with very high ...
Pulsar Measurement manufactures and supplies a range of instrumentation for non-contacting level, volume, open channel flow, pipe flow, sludge interface, and pump control [1] [2] to the Water / Wastewater, Food Production, and Process Automation industries. Pulsar also manufactures electro-mechanical components.
Internal block diagram. A mass flow controller (MFC) is a device used to measure and control the flow of liquids and gases. [1] A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates.
Sonar flowmeters have the capacity of measuring the velocity of liquids or gases non-intrusively within the pipe and then leverage this velocity measurement into a flow rate by using the cross-sectional area of the pipe and the line pressure and temperature. The principle behind this flow measurement is the use of underwater acoustics.
