For bypass applications with magnetic level indicator

The TORRIX bypass is the ideal sensor for level measurement in tanks with magnetic level indicators. The TORRIX is mounted on the outside of the bypass, and picks up the magnetic field and delivers the level inside the bypass, without any contact with the liquid. Many magnetic level indicators can be retrofitted with a TORRIX.

Application Examples


Bypass applications with magnetic level indicator

In magnetic level indicator applications, the magnetic indicators are actuated by the magnetic field of a float in the interior of the bypass. The magnetic field of this float can also be measured by a TORRIX which is mounted on the exterior of the bypass. The TORRIX can therefore measure the level without media contact and without additional intervention in the process tank. Many magnetic level gauges can be retrofitted with a TORRIX.
