U-channel guard protects sight tubes

An Elesa (UK) product story
Edited by the Engineeringtalk editorial team Aug 22, 2008

HCL column level indicators feature a U-shaped aluminium channel running around three sides of the tube and also carrying the easy to read graduated contract scale.

Elesa's HCL column level indicators are available in lengths from 300 to 2000mm for oil tanks or other bulk liquid containers.

As such, mechanical protection of the sight tube is an important feature, and this is provided in the HCL by means of a U-shaped aluminium channel running around three sides of the tube and also carrying the easy to read graduated contract scale.

The HCL series construction enables this U-channel to be rotated 90 degrees in installation, so enabling reading from the side.

In addition, a variety of tube/end/O-ring materials are available to suit unusual liquid specifications.

HCL variants are also possible with float, minimum level signal, remote alarm, remote read using normally closed (NC), normally open (NA) or changeover contacts.
