In a Coriolis mass flowmeter, the swinging is generated by vibrating the tube(s) in which the fluid flows. The amount of twist is proportional to the mass flow rate of fluid passing through the tube(s). Sensors and a Coriolis mass flowmeter transmitter are used to measure the twist and generate a linear flow signal.Coriolis Mass Flow meters are specially designed and manufactured to meet the demands of difficult applications. These flow meters are available for measuring mass flow and density of liquids, slurries and gases. They use the Coriolis force for direct mass flow measurement of any fluid. Since mass is measured directly, no calculations involving density or volume are required. Measurements are thus immune to variations in pressure, temperature, density, viscosity, electrical conductivity or the presence of gas bubbles or solid particles in the fluid medium.Simultaneous direct measurement of Mass Flow, Density and Temperature with volume, concentration, Brix & Baume as derived parameters are available as standard features, and upto 3 current outputs as an option.

A water meter is a device used to measure the volume of water.Water meters are used to measure the volume of water used by residential and commercial buildings that are supplied with water by a public water supply system. Water meters can also be used at the water source, well, or throughout a water system to determine flow through that portion of the system. In most of the world water meters measure flow in Cubic metres (m3) or litres. Some electronic meter registers can display rate-of-flow in addition to total usage.There are several types of water meter in common use. Selection is based on different flow measurement methods, the type of end user, the required flow rates, and accuracy requirements.

A velocity-type meter measures the velocity of flow through a meter of a known internal capacity. The speed of the flow can then be converted into volume of flow for usage. There are several types of meters that measure water flow velocity to determine totality usage. They include jet meters (single-jet and multi-jet), turbine meters, propeller meters, and mag meters. Most velocity-based meters have an adjustment vane for calibration of the meter to required accuracy.

STANDARDSConforms toISO 4064, Class B.

Vortex flow measurement involves placing a bluff body (called a shedder bar) in the path of the fluid. As the fluid passes this bar, disturbances in the flow called vortices are created. The vortices trail behind the cylinder, alternatively from each side of the bluff body. This vortex trail is called the Von Krmn vortex street after von Krmn's 1912 mathematical description of the phenomenon. The frequency at which these vortices alternate sides is essentially proportional to the flow rate of the fluid. Inside, atop, or downstream of the shedder bar is a sensor for measuring the frequency of the vortex shedding. This sensor is often a piezoelectric crystal, which produces a small, but measurable, voltage pulse every time a vortex is created.Vortex meters are used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralised water, solvents, heat transfer oils, boiler feed water, condensate, etc.
