Level Switches Multi-Point - 1

Float Type Multi-Point Custom Length – 1 to 7 Levels GEMS Custom Length level switches are extremely versatile. Within this section you’ll find level switches that are configured to your custom specifications at the GEMS factory. Single Actuation Levels LEVEL SWITCHES – MULTI POINT When one of our Standard Single Level switches doesn’t extend to the length you need, no problem, order a Custom Length single level switch from this section. Specify lengths to over 11 feet. These units also offer you the flexibility of mounting a low, or intermediate level switch from the tank top rather than a bottom or side mounting. Levels. As Lengths to GEMS Custom Length models can be Many as Seven over 11 Feet configured with “up to seven” independent switch actuation levels, depending on the series type. These “multi-station” units offer the most practical way to monitor multiple liquid level points within a single tank. Only a single entry point into the tank is required, and all electrical wiring emanates from a single source. In addition to tracking changing level points of a single liquid within a tank, “multi-station” level switches are ideal for monitoring liquid interfaces and emulsions in vessels simultaneously containing two or more liquids. Contact GEMS with your liquid specifications for further information on this type of application. Typical Application GEMS Custom Length Switches are used to monitor water, diesel or lube oils, chemicals and petrochemicals. Pump-Up/Pump-Down Operations Pump-Up/Pump-Down with Intermediate Level Indication ANNUNCIATOR HIGH LEVEL HIGH LEVEL CONTROLLER INTERMEDIATE LEVELS Using GEMS Custom Length level switches, junction boxes, solid-state relays and annunciators, complete liquid level control systems are easily configured. Liquid Interface Monitoring In addition to monitoring the surface level of liquids, many GEMS Level Switches can be used to sense the interface point between dissimilar liquids sharing the same tank. Monitoring water condensation in fuel storage tanks, and separating chemical emulsions in process systems are two typical application examples. Multi-station level switches can be configured to monitor this interface point in addition to high and low liquid levels. Contact Gems Sensors Inc. with your specific application.
