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.
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 ...
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 ...
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.
Note transmitter on one side of the column and receiver on opposite. An ultrasonic pulse velocity test is an in-situ , nondestructive test to check the quality of concrete and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an ultrasonic pulse passing through a concrete ...
