Model 060 Model 040 Model 025

The Hallikainen Rotameters are variable area flowmeters for liquid or gas service. Fluid enters through the botton inlet, flows upwards through the glass tube and out at the top. The rote of flow is indicated by the posi- tion of The ball float inside a tapered tube. The ball will rise with increasing flow, drop with decreasing flpw. Readings ctre taken from the centre of the ball. The Rotatneter frame can be supplied with a needle valve to con- trol flow. For gas applications it is preferable to have the valve in the top outlet block.

These Rotameters can be provided with regulators which maintain a constant differential pressure across the Rotameter valve. Rate-of-flow can thereby be held constant despite changing supply or discharge pressure.

The Hallikainen Rotameter frames were designed to give excellent all-round visibility, and easy access to the tube. A plpstic shield protects the glass tube which can be easily removed from the frame if the compression nut is screwed tight against the connection block. A single frame will accept a range of tubes with varying flow capacities. When the tube is replaced the compression nut is screwed down until the tube cannot be rotated by the fingers.

The borosilicate glass tubes clre available in three lengths: 2%", 4" and 6". The 2'/," and 4" tubes have plain tapers, the 6" tubes are rib guided for greater accuracy.
