ABBITZ Model 311A Indicator


        Barton® Model 200A Indicator

The ABBITZ Model 311A indicator measures differential pressure, fluid flow rate, or liquid level. For fluid flow measurements, the indicator is connected by piping to the low and high-pressure sides of orifice plates, venturis, flow tubes or a similar device located in the process run. For liquid level applications, variations in the level of the liquid within the process vessel produce changes in differential pressure used to indicate the liquid height. The indicating pointer travels through a 270 degree arc over a six-inch diameter scale. The precision jeweled movement has a easily accessible micrometer screw for range adjustment. Zero adjustment via the pointer hub can be made without removing the scale plate or pointer. Additional range and linearity adjustments are accessible after removal of the scale plate. The ABBITZ model 311A differential pressure indicator is a drop in alternative for the Barton model 200A DP indicator.
