Product Specifications:

A single case size is used for most ranges of Dwyer gauges. They can be hung or mounted with standard hardware supplied. Although they are designed for vertical position, full ranges above 1 inch may be used at any angle by simply re-zeroing. However, for maximum accuracy, they must be calibrated in the same position in which they are used. These characteristics make Dwyer gauges ideal for both stationary and portable applications. A 4-9/16” hole is required for panel mounting. Complete mounting and connection fittings plus instructions are furnished with each instrument.     

.Medium/High Pressure Models 
Installation is similar to standard gauge except that a 4-13/16” hole is needed for flush mounting. Because medium and high pressure models have large cases, they will not fit in portable cases. Above 1” differential pressure of full scale can be finely tuned zeroing after installation in every applied angle (EX: 45° bevel) The gauge can be used as fixed or mobile angles (Below 1” differential pressure of full scale which concerned to limited fine –tuning is not suitable.)
