Metal tube variable area flow meters (rotameters) are mainly applied when high pressure, temperature or corrosive conditions preclude the use of conventional glass tube. They are designed to measure flow rate of liquids, gases & steam under critical conditions. Flowtech is known for the reliable and accurate metal tube rotameters that it provides.
"flowtech" glass tube variable area flow meters (rotameters) are intended for general in-line and for by-pass metering applications (i.E. For gas & liquid) where operating conditions are with the limitations of glass metering tubes. It consists of a tapered tube, with a float inside that is pushed up by fluid flow and pulled down by gravity. Flowtech is a leading manufacturer for the glass tube rotameter.
Flowtech make electromagnetic flow meter are intended for measuring flow of electrically conductive liquids in closed pipe lines where the magnetic flux permeates the entire cross sectional area of the liquids flow. Electromagnetic flow meters measure electromotive forces to determine liquids velocity using faraday's law of electromagnetic induction and compute the flow rate using equation of conductive liquids having minimum conductivity of 5 micro siemens / cm and are relatively immune to the effects of temperature , pressure , viscosity & density of the flowing liquid.
