An LVDT (Linear Variable Differential Transformer) Variable Area Rotameter, is a meter designed to measure the flow rate of a fluid or gas.
Mechanism The flow meter utilizes a unique combination of a tapered metering cone in series with a piston. The position of the metal piston is sensed by the LVDT circuitry and is then translated into a flow rate. This non linear signal can be directly displayed or linearized with an electrical output.
Benefits Advantages include the ability to externally measure very low flow rates.Measurements & Control New Products June, 1994IAN product news June 1994 v.42 N.6Pollution Equipment news August 1994 v.27 N.5
