FOR ACCURATE AND ECONOMICAL MEASUREMENT & CONTROL OF FLUID FLOW

Spink Controls offer an Industrail flowmeter used to measure flowrate of liquids and gases. it operated on the Variable Area Principle, where the fluid flow raises a float in taper tube increasing the area of passage of fluid. The greater the flow, the higher the float is raised The height of float is raised by a combination of the buoyance of the liquid and velocity head of the fluid. With gases, the buoyancy is negligible,and float responds to the velocity head alone.

The taper glass tube is formed of Borosilicate glass of extremely high accuracy of bore obtained by collapsing the taper tube while in hot and plastic state on pricision ground and polished mandril. The tubes are then annealed in furnace to relieve the stress formed during manufacturing.

Float of various configuration and material are used for a wide range of application depending upon flowrate, viscosity and turbidity of fluid. The float has a sharp metering edge where the reading is observed by means of scale mounted along side of the tube. The scale of rotameter is calibrated to directly read the fluid flow. The flowrate for any variable area flowrate can be expressed as
