ITT Barton Model 450C Indicator

The ITT Barton Model 450C indicates low DP in high static pressure applications. Its 4-1/2" dial provides excellent readability with economy of space. The ITT Barton M450C is a commercial version of the ITT Barton M316C, used by the U.S. Navy for shipboard measurement of DP, flow, and Liquid level.

• Case: Aluminum (NEMA 4) or 316SST (NEMA 4X), Weather-proof
• Dial: 4-1/2 inch, 270° arc
• Actuated by the 224C DPU Indicating Mechanism

The indicating pointer traverses a 270° arc, providing excellent readability. It is driven by a precision, jeweled rotary movement that employs a thermally stable Ni-Span-C hair spring. The movement has a micrometer screw for range adjustments. Zero and range adjustments can be made without removing the scaleplate or pointer. Linearity adjustments are easily accessible after removal of the scaleplate.


The 4-1/2 inch diameter scale can be graduated uniformly for DP or level, or square root for direct reading of flow rate. Special scales for indicating liquid quantity in tanks can be provided.
