Level Transmitter or Level Gauge Calibration
Our Services
Optimal performance of a level transmitter is critical in any industrial operation that involves storing bulk quantities of fluids or fluidized solids. To maximize the performance of their systems, companies must understand – and utilize – leading calibration techniques.
Calibrating level transmitters will help protect against problems related to the accounting of materials and against damage to tanks and pumps that incorrect measurement can cause.
Calculate the Differences Between Your Test Fluid and Your Process Fluid
For the vast majority of applications, companies will not be using their process fluid to complete the calibration work. In some cases, the process fluid is unsuitable for testing. In other cases, the fluid might be wasted during the testing procedure, and so the company will use water or another less expensive fluid to complete their calibrations.
Each level transmitter will be set by its manufacturer for a fluid-specific gravity. This means companies must calculate the difference in buoyancy between the fluid they use in their processes and their test fluid. The typical calculation for this range would be the following:
process fluid specific gravity / water specific gravity x transmitter level range
Determine Acceptable Tolerance Level
In beginning the calibration work, it’s important to understand the acceptable tolerance level for the process. One of the benefits of specifying a tolerance level at the inception of calibration work is that it allows team members to work within these parameters. This can help eliminate many of the mistakes made when calibrating level transmitters and can act as a guide for equipment performance moving forward.
