Depending on the selected ordering code the following models are available: a) model 264DR which allows a differential measurement using either two remote seals of same type and size or one remote seal (on positive or negative side) and a standard threaded connection 1/4in NPT on flange or 1/2in NPT through adapter, for the wet or dry leg on the side opposite to seal. b) models 264PR or 264VR allowing gauge or absolute measurement respetively with the reference side at atmosphere or at vacuum. The other side which can be the positive or negative (high or low pressure side) features the required remote seal.
