Barton 450C Indicator

Employed by the U.S. Navy, the Barton® Model 450C Indicator determines flow, liquid level, and DP and is also used to detect low DP in elevated static pressure applications. It exhibits a compact 4-1/2 inch dial with an aluminum (NEMA 4) or 316SST (NEMA 4X) case, designed to withstand the elements. A commercial version of the M316C, the M450C features an easy-to-read indicating pointer that travels a 270° arc and is activated by a 224C DPU indicating mechanism.

• 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 precision, a jeweled rotary movement that employs a thermally stable Ni-Span-C hairspring. The movement has a micrometer screw for range adjustments. Zero and range adjustments
can be made without removing the scale plate or pointer. Linearity adjustments are easily accessible after the removal of the scale plate.

Scales

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.

Barton 316C 4.5-inch DP Indicator

Engineered to align with MIL-S-901C Shock Grade A and MIL-STD-167 Vibration criteria, the Barton® Model 316C 4.5-inch DP Indicator is a distinctive version of the M450C. The U.S. Navy commonly uses this device to determine DP, flow, and liquid level for onboard installations.
