Electronic Level Gauge for LPG – C-Flex

Rotarex ELG C-Flex is an electronic level gauge with a highly flexible capacitive level probe for stationary tanks and cylinders. It is compatible with standard connections and features a replaceable, waterproof display that can be rotated for improved visibility.

SUPERIOR ACCURACY

No more doubts about your LPG level. Compared to a traditional mechanical gauge, which has limited precision, the Rotarex SRG digital capacitive gauge gives you an accurate and detailed measurement across the entire tank content. The DIMES gives you a superior accuracy +/- 1% (over full scale) compared to mechanical devices, eliminating any guesswork.
Superior Accuracy
Hassle-free retrofit

HASSLE-FREE RETROFIT

Replace your old mechanical pressure gauge with a modern digital capacitive pressure gauge in just a few simple steps. Monitor your LPG (propane, butane) level easily with this advanced digital pressure gauge that integrates seamlessly into your existing installation. Plus, you can easily cut the sensor yourself to fit the exact dimensions of your tank, ensuring a perfect fit for your setup.

ENHANCED RELIABILITY AND DURABILITY

The absence of moving parts means that no part of the manometer is likely to wear out, jam, or deteriorate over time, increasing its reliability and service life. Get the most out of your electronic level gauge.
