Products > Level > Indicators > Float Operated & Pneumatic Gauges
Two simple styles of level indicator for monitoring tank contents. The UNIMESS is a spring loaded float operated gauge suitable for tanks between 900 & 2000mm high. This float operated device is adjustable on site for different liquid density and tank heights. It is mounted on top of the tank. The UNITOP is a pneumatic indicator which can be mounted up to 50m from the tank monitored. A manual pump pressurises the air in the bubbler tube, until it overcomes the liquid back pressure. This is then monitored on the dial, which can be calibrated according to tank height and liquid/oil density. The PVC tube kit includes a tank adaptor (1/2" BSP) and a weight for the end of the tube. |  |
