Three-valve manifold simplifies installation of wet/wet differential pressure transmitter

Simplify Installation of Wet/Wet Transmitter

When using differential pressure transmitters in fluid applications, it is essential to periodically make sure that there is no air in the system, as this can cause erroneous readings. Unfortunately, the necessary three-valve bleed system is often expensive and large, making installation difficult and bulky. For this reason, Dwyer Instruments, Inc. offers the 3V option on all Series 629 Wet/Wet Differential Pressure Transmitters. This compact, lightweight, and economical bleed manifold is shipped factory-installed on the 629, eliminating the hassle of constructing a custom apparatus. The 629, when combined with the three-valve option, makes for an ideal setup to monitor hydraulic filter clogging or other fluid pressure sensing applications.
