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 ...
Parshall flumes (right) alongside other types of flow meters. The Parshall flume is an open channel flow-metering device that was developed to measure the flow of surface water and irrigation flow.

Sick AG was founded in 1946 by Erwin Sick (1909–1988); he had received a license from the then-US-managed local government to operate his engineering firm.. The economic breakthrough came in 1952 with the volume production of the accident-prevention light curtain, presented at the International Machine-Tool Trade Fair in Hanover.
Ultrasonic flow meter; Mass flow meter (Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.
A velocity-type meter measures the velocity of flow through a meter of known internal capacity. The speed of the flow can then be converted into a volume of flow to determine the usage. There are several types of meters that measure water flow velocity, including jet meters (single-jet and multi-jet), turbine meters, propeller meters and mag ...
