It operates on the principle of variable area; the fluid in the metal tube raises the float in the taper tube increasing the area of passage of fluid. By a magnetic coupling the inner float movement through a series of linkages and counter weight. The tube and the float combination determines the flow rate. The inner float magnetic field is detected by the high sensitive magnetic field detection sensor, enable us to show the digital readout. As such this flowmeter does not require any electrical connection, since it operates on battery. This got an inbuilt two wire transmitter just provide 24 vdc. and take 4 – 20 ma signal.

It operates on the principle of variable area the fluid in the glass tube raises the float in the taper tube increasing the area of passage of fluid. The float moves up in proportion to the rate of flow of fluid and get stabilized when the weight of the float is balanced by the upward hydraulic force. The tube and the float combination determines the flow rate. The float has a sharp metering edge where the reading is observed by means of scale mounted along side of the tube. The taper glass tube is formed of annealed borosilicate glass of extremely high accuracy bore.

The orifice plate with flange assemblies are employed for measuring the rate of flow or quantity of moving fluids like liquids, gases or vapours. The orifice plates are designed as per BS1042-1981 / ISO 5167 & L K. SPINK STANDARDS. When a device such as an orifice plate in a pipe line through which a fluid is flowing, as static pressure difference exists between the upstream side & the downstream side of the device is geometrically similar to one on which direct calibration has been made, the conditions of use being the same, the rate of flow may be determined from a knowledge of the circumstance under which the device is being used.

The ori-flow meter measures flow by inserting an orifice at part of the piping, generating differential pressure before and behind the orifice by means of the flow, and extracting this differential pressure by a suitable method. Differential pressure (p1-p2) of main orifice & the flow q have shown in equation given below. The flow is proportional to square root of the differential pressure.

The pitot tube produces a Differential pressure (DP) signal proportional to the square of the flow rate in accordance with Bernoulli`s theorem. This signal has two components, the high pressure (HP) and the low pressure (LP).
