'dead load'

NRG GLOBAL INSTRUMENTS MAKE Glass Tube Variable Area Flow Meters (Rotameters) are intended for general in line and ByPass metering applications (i.e. for Gas & Liquid) where operating conditions are with the limitations of Glass metering tubes. These are the principle of Variable Area. The float moves freely up and down tapered borosilicate glass with fluid flow from bottom to top. The float takes up a position where buoyancy forces and 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. 2. Principal of Operation When fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 is created between upper and lower side of the float. The float moves upwards by a force obtained by multiplying the pressure differential by the maximum cross-sectional area of the float. Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which the differential pressure decreases. Upward movement of float stops when the dead load is dynamically balanced by the differential pressure.

NRG GLOBAL MAKE Metal Variable Area Type Flow Meter are designed to measure flow rate of liquids and gases under critical conditions. It consists of a tapered metal tube, an indicating assembly and float. A magnet encapsulated in float couples with rotating magnets are connected to an indicating pointer. Henceforth, the movement of the float is accurately indicated in terms of flowrate. They are intended for application where high pressure, temperature or corrosive conditions preclude the use of conventional glass tube. These are all Metal Variable Area Type Flow meter design to measure flow rate of Liquids & Gases under critical conditions. It consists of a tapered metal tube, an indicating assembly and a float. A magnet encapsulates in float couples with rotating magnets connected to an indicating pointer, thus the movement of the float, is accurately indicated in terms of flow rate. 2. Working Principle When fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 is created between upper and lower side of the float. The float moves upwards by a force obtained by multiplying the pressure differential by the maximum cross-sectional area of the float. Based on Bemoulli's theorem, the principle mentioned above can be theoretically expressed as follows. Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which the differential pressure decreases. Upward movement of float stops when the dead load is dynamically balanced by the differential pressure. Tapering of metering tube is so designed that the vertical movement of the float becomes linearly proportional to the rate of flow and the scale is provided to read the position of the float, thusgiving birth to flow rate indication.
