Model 2100 DLS with High-Level Shut-In

Model 2100 DLS with High-Level Shut-In

Categories: Digital Level Sensors (DLS)

The Model 2100 DLS with High Level Shut-In delivers consistently accurate measurements of different types of fluids in both hazardous and non-hazardous environments. Multiple fluid densities and temperatures do not affect measurement. The DLS with High Level Shut-In effectively measures the level and temperature of a variety of liquids, including Crude oil, Diesel, Kerosene, Condensate, Gasoline, Water, and Others.

With the addition of a third float, the Model 2100 DLS with High Level Shut-In provides two digital outputs, one for a high level alarm and one for a high-high level shut-in. This is all accomplished with two distinct circuits: one for normal continuous level and temperature measurement—the other for high level alarm and shut-in. The high level alarm requires no power and, unlike competitor’s sensors, is not affected by power outages. The high level alarm and shut-in feature is always active.

Accurate and Versatile

The Model 2100 DLS with High Level Shut-In delivers consistently accurate measurements of different types of fluids in both hazardous and non-hazardous environments. Multiple fluid densities and temperatures do not affect measurement. The DLS with High Level Shut-In effectively measures the level and temperature of a variety of liquids, including Crude oil, Diesel, Kerosene, Condensate, Gasoline, Water, and Others.

These digital level sensors are suitable for production monitoring, inventory control, leak detection (in stagnant tanks), high level alarm and well shut-in. Communications to SCADA systems can be digital or analog and the DLS works with many wireless systems using Modbus RTU protocols and ASCII.

One Device Does it All—Level, Temperature, High Level Shut-In

With the addition of a third float, the Model 2100 DLS with High Level Shut-In provides two digital outputs, one for a high level alarm and one for a high-high level shut-in. This is all accomplished with two distinct circuits: one for normal continuous level and temperature measurement—the other for high level alarm and shut-in. The high level alarm requires no power and, unlike competitor’s sensors, is not affected by power outages. The high level alarm and shut-in feature is always active.

An integrated test fixture, allows for testing of the high level shut-in feature at any time and provides the added safety benefit of not having to open the tank hatch. A teflon-coated string attached to the third float provides a means to manually raise the float and trigger the high-level output/alarm.
