DIN 4754-3:2015-03

The purpose of this standard is to determine certain fundamental requirements in respect to the technical implementation and testing of level controllers in heat transfer installations working with organic heat transfer fluids. The tests and test methods described in this standard may also be applied to type and acceptance tests if required. Owing to revision of DIN 4754:1994-09, a revision of DIN 32728:1981-02 was also necessary. This incorporated knowledge and experience concerning level controllers with the state of the art as well as current legal regulations having been taken into consideration.
