Vibrating Fork Level Switches Provide Continuous Protection

Modern level instrumentation makes it easy to provide an accurate, reliable and continuous measurement of reservoir level. Operator rounds are eliminated, saving time and reducing costs, and since the operators are not exposed to process conditions, the risk of injury or accidents is reduced. In addition, any potential human error when checking and recording lubricating oil levels is removed.

Vibrating fork level switches are ideal for low level and high level alarm applications. The switches operate on the principle of a tuning fork, whose frequency varies depending on whether the fork is immersed or dry. Unlike many other level switch technologies, the vibrating fork technology does not have moving parts that can wear or stick and is therefore less prone to failure.

However, with many pumps installed in difficult to reach or remote locations, the installation of traditional wired devices to provide a low level alarm often requires the difficult and costly installation of instrumentation wiring and its associated trenching, conduit runs and wiring trays.

Low Level Monitoring with Wireless Devices

Wireless technology, with its easy-to-install devices and easy-to-configure hardware and software, provides the opportunity for continuous low level monitoring with high accuracy and reliability, helping to prevent serious incidents by detecting a low oil level condition before it results in damage to the pump bearings. The latest generation of wireless enabled vibrating fork level switches feature built in diagnostics and fast update rates that make them suitable for a wide range of critical applications.

For example, Emerson’s Rosemount 2160 Wireless Level Switch provides one second update rates, extending the range of suitable level control applications to include fast moving applications where the liquid level is changing rapidly. Enhanced diagnostics will detect conditions such as a damaged fork, damaged sensor, media build up on the fork and excessive corrosion on the fork.
