The Dall tube is a shortened version of a Venturi meter, with a lower pressure drop than an orifice plate. As with these flowmeters the flow rate in a Dall tube is determined by measuring the pressure drop caused by restriction in the conduit. The pressure differential is typically measured using diaphragm pressure transducers with digital readout.
Both mass flow and density measurements depend on the vibration of the tube. Calibration is affected by changes in the rigidity of the flow tubes. Changes in temperature and pressure will cause the tube rigidity to change, but these can be compensated for through pressure and temperature zero and span compensation factors.
Temperature, pressure, and humidity sensors can be used to feed data into an automated bell PLC, and calculations for meter proofs can be handled by a computer or electronic device programmed for such a purpose. In the early 1990s, the PLC was replaced by PACs (Programmable Automated Controls) and modern computer systems.
A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston. Deadweight testers are secondary standards which means that the pressure measured by a deadweight tester is defined through other quantities: length, mass and ...
Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. Pressure sensors can vary drastically in technology, design, performance, application suitability and ...
Endress+Hauser Optical Analysis, Inc. is a manufacturer of optical-based gas sensors for the industrial process, environmental monitoring and clean technology markets. The company's sensors measure the absorption of laser light at specific wavelengths to detect carbon dioxide and water vapor in industrial process control and environmental monitoring applications.
The Clark electrode [1] [2] is an electrode that measures ambient oxygen partial pressure in a liquid using a catalytic platinum surface according to the net reaction: [3] O 2 + 4 e − + 4 H + → 2 H 2 O. It improves on a bare platinum electrode by use of a membrane to reduce fouling and metal plating onto the platinum. [4]
