Signet 2552 Metal Magmeter Flow Sensors

GF Signet


* Customer must determine stack height (ball valve, nipple, weldolet, etc.). Refer to Sensor Selection image to determine "A" dimension. Sensor tip must be positioned at 10% of pipe I.D.

** 1-1/4 inch process connection is the standard thread size on the 3-2552-2X-X-XX: For the 2552-3 the 1-1/2 inch process connection is standard and the 1-1/4 inch is available as a special order.
