Profile: Flowtech Instruments Services is a manufacturer of process control equipment. We are an ISO 9001 certified company. We manufacture flowmeters, level instruments such as indicators, gauges, switches & transmitters, sight flow indicators, and manometers. Glass tube variable area flow meters (rotameters) are intended for general in-line & by-pass metering applications, where operating conditions are with the limitations of glass metering tubes. The float moves freely up & down inside the tapered borosilicate glass with fluid flow from bottom to top. The float takes up a position where buoyancy forces & the float weight are balanced in proportion to flow rate. The vertical position of the float as indicated by scale is the measure of the instantaneous flow rate. Heavy duty tubular liquid level indicator is a simple & reliable device for direct reading in atmospheric or pressurized tank applications. This indicator eliminates trouble giving threaded joints of conventional gauge glass cock.
