Key Considerations for Selecting and Maintaining Level Gauges

Key Considerations for Selecting and Maintaining Level Gauges

2026-05-09

Proper selection and regular maintenance are essential for ensuring the measurement accuracy of level gauges.

Proper selection and regular maintenance are essential for ensuring the measurement accuracy of level gauges.

Selection Criteria

Properties of the medium: Is it corrosive, prone to crystallization, or prone to foaming?

Process conditions: Pressure and temperature range inside the vessel

Installation Environment: Presence of vibration, steam, or dust interference at the site

Output Requirements: Local display or remote signal.

 

Installation Guidelines

Ensure the level gauge is installed vertically to minimize tilt-induced errors

Install shut-off valves on connecting pipes to facilitate maintenance and disassembly

Ensure the measurement range covers the high and low level alarm points required by the process.

 

Routine Maintenance

Regularly clean the glass tube or magnetic flip-plate to prevent dirt buildup from affecting readings

Inspect seals for signs of aging or leakage

Verify that the remote signal matches the local display

For non-contact instruments, clean any deposits from the probe surface

Through proper selection and standardized maintenance, level gauges can provide stable level monitoring under various operating conditions.

Understanding Digital Vortex Flowmeters: A Comprehensive Guide

Digital vortex flowmeters are advanced instruments used for measuring the flow of gases and liquids in a wide range of applications. They are based on the principle of vortex shedding, where flow past a bluff body generates vortices that are periodic in nature. These vortices are sensed by the flowmeter, and their frequency is directly proportional to the flow velocity. This technology offers seve
