ISO) Technical Committee 113 (hydrometry) publishes standards that apply to an open channel flow sensor. ISO/TS 24154 applies to the measurement of river velocity with acoustic Doppler profilers. Open channel flow sensors that meet the requirements... Learn More

...in aerosols, dispersion, emulsions, powders, and other samples. Particle analysis is also used to determine particle velocity and surface charging. Particle velocity measurements are important in understanding spray and aerosol processes such as paint... Search by Specification | Learn More

...displacement (PD), velocity, and true mass. Differential pressure flow meters obtain a liquid’s flow rate by measuring the pressure differential and extracting the square root. Examples include orifice plates, Venturi tubes, flow nozzles, Pitot... Search by Specification | Learn More

Tachometers are used to measure the velocity of a rotating object. They operate on the principle that a driven motor (i.e., a motor operated as a generator) produces a voltage that is proportional to the angular velocity of the motor shaft Search by Specification | Learn More

Vortex flow meters are flow sensors that detect the frequency of vortices shed by a bluff body placed in a flow stream. The frequency of the vortices is proportional to the flow velocity. Search by Specification | Learn More

Magnetic speed sensors rely on a magnet as the sensing element or sensed target to capture rotational or linear speed. They are typically used as gear tooth speed sensors or incorporated into stroboscopes or tachometers. Search by Specification | Learn More

...into an isolated analog voltage signal that is suitable for remote indication and control applications. Tachometer generators and tachogeneratorsare also used in servo systems to supply velocity or damping signals and may be mounted on or in the same... Search by Specification | Learn More

...of the water to the ocean floor, the speed of water currents, and the height of tides. An acoustic doppler current profiler is a sonar device that uses transducers to detect and record the water’s current velocities across a range of depths... Learn More

...inferentially by measuring the liquid's velocity or the change in kinetic energy. Velocity depends on the pressure differential that is forcing the liquid through a pipe or conduit. Because the pipe's cross-sectional area is known and remains constant... Search by Specification | Learn More

...to the material velocity. Nutating disc meters use media pressure to rock a disc in a circulating path without causing the disc to rotate about its own axis. A pin that extends from the disc is connected to a counter that monitors the disc’s rocking motions... Search by Specification | Learn More

They are cost effective and require no extra machining. However, they tend to involve a high degree of surface area, which can disrupt flow. They are not recommended for use in high velocity flow systems. Stepped shank thermowells have less surface... Search by Specification | Learn More
