Description

The Spirax Sarco WG2 level gauge enables an instant visual check

to be made of liquid level in tanks and process vessels.

It consists of a glass tube (plastic also available) mounted in top

and bottom support arms, with packing seals and washers to prevent

leakage and accommodate expansion. The bottom arm incorporates

a three port plug cock to allow isolation and checking of gauge

operation.

An intermediate arm provides additional support and sealing for

gauges with centres longer than 1100 mm, and enables two unequal

length tubes to be used together to give a wide choice of overall

lengths.

Two protector rods mounted either side of the tube reduce the risk

of accidental damage. For greater protection 'C' section protectors

are also available (used with rods).
