Glass Tube Rotameter: It is basically a variable area flow meter. The differential pressure across the annulus area is constant and the flow rate is measured as a function of the annulus area created by ‘Float’ position.

Glass Tube Rotameter with Transmitter: It is basically a variable area flow meter. 2-Wire Transmitter is provided for conventional Glass Tube Rotameter. The O/P is 4-20mA which is proportional to flow

Metal Tube Rotameter with Transmitter: It is basically a variable area flow meter. 4-Wire Transmitter based on ‘Hall Effect’ is provided for conventional Metal Tube Rotameter. The O/P is 4-20mA which is proportional to flow rate.

By-Pass Rotameter: It is an inference type flow meter. Because of the differential pressure, this is generated due to Orifice Plate; a branch of flow flows through the by-pass line. By measuring the flow from by-pass line we can estimate the flow through the Main Line.

Acrylic Rotameter: It is basically a variable area flow meter. The differential pressure across the annulus area is constant and the flow rate is measured as a function of the annulus area created by ‘Float’ position. It is made from a Acrylic Block.

Low Flow Rotameter: It is basically a variable area flow meter. Used for low flow ranges

Low Flow Rotameter with DP Regulator: It is basically a variable area flow meter. Used for Nitrogen Purging in a tank. The flow remains constant irrespective of the downstream pressure.

Tansa Switch can be also used
wherever Bi-stable conditions
are to be sensed.
