Application Notes

Here's how some of our customers used this product.

Hot Water Level Measurement in an Unvented Tank

The Background: The customer is a piping fabricator working on a project that requires continuous level measurement inside a hot water tank.

The Problem: The tank is not vented so the hot water results in a build-up of pressure and water vapor which prevents the use of pressure sensors or ultrasonic sensors to measure the level.

The Solution: Guided wave radar is unaffected by tank pressure or vapor presence and works well in these difficult conditions. The Krohne Optiflex 1100C level meter delivers high performance at a price similar to pressure or ultrasonic level technologies. Additionally, the Optiflex 1100C is field configurable to the customer’s specific application making it a universal level solution and easy to deploy in a single configuration for multiple measurement points.
