Rotameters are the most widely used type of variable-area (VA) flowmeter. In these devices, the falling and rising action of a float in a tapered tube provides a measure of flow rate (see Figure 1). Rotameters are known as gravity-type flow meters because they are based on the opposition between the downward force of gravity and the upward force of the flowing fluid. When the flow is constant, the float stays in one position that can be related to the volumetric flow rate. That position is indicated on a graduated scale. Note that to keep the full force of gravity in effect, this dynamic balancing act requires a vertical measuring tube.

Other forms of gravity-type VA meters may incorporate a piston or vane that responds to flow in a manner similar to the float's behavior. All these devices can be used to measure the flow rates of most liquids, gases, and steam. There are also similar types that balance the fluid flow with a spring rather than gravitational force. These do not require vertical mounting, but corrosive or erosive fluids can damage the spring and lead to reduced accuracy.

  • Simple meter placement - floating chamber IP 68 (NEMA 6P) design ensures continuous filterless performance regardless of position or in-line piping stresses, even when buried underground

  • Low pressure loss - unrestricted flow tube ensures minimal pressure loss even at high flow rates and reduces overall network system pressure, helping to prevent leakage from burst pipes and excess stress placed on pumping stations

  • Zero maintenance – no moving parts and 10-year battery life

  • Bi-directional measurement - only one meter required for measurement in both directions

  • Installation requires 0D inlet to and outlet from the sensor - eliminating concerns about where the meter is installed

  • Intelligent meter – capable of leak detection, data logging and error self-detection

  • Remote capabilities – stay up-to-date on measurement data without having to visit the site through optional GSM/GPRS Wireless Communication Module

A Rotameter is a form of variable area flow meter which has a simplistic operation whereby a liquid or gas passes through a tapered tube. In order for this gas to pass through the tube it must first raise a float held within the tube. ... In both cases, the greater the flow then the higher up the tube the float moves.
