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.
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 ...
The "Laser Ultrasonic" technique is part of those measurement techniques known as "non-destructive techniques or NDT", that is, methods which do not change the state of measurand itself. Laser ultrasonics is a contactless ultrasonic inspection technique based on excitation and ultrasound measurement using two lasers.
The first ultrasonic thickness gauge was made in 1967 by Werner Sobek; [citation needed] a Polish engineer from Katowice. This first ultrasonic thickness gauge measured the velocity of the waves it emitted in particular test samples, it then calculated the thickness in micrometers from this speed measurement by an applied mathematical equation.
Liquid level floats, also known as float balls, are spherical, cylindrical, oblong or similarly shaped objects, made from either rigid or flexible material, that are buoyant in water and other liquids. They are non-electrical hardware frequently used as visual sight-indicators for surface demarcation and level measurement. They may also be ...
A procedure for ultrasonic testing is outlined in ASTM C597 - 09. [9] In India, till 2018 ultrasonic testing was conducted according to IS 13311-1992.From 2018, procedure and specification for Ultrasonic pulse velocity test is outlined in IS 516 Part 5:Non destructive testing of concrete Section 1:Ultrasonic Pulse Velocity Testing. This test ...
