Series 25D Flange Mount Accutube

Series 25D Accutube - Double Mount. The Accutube Series 25D standard probe is constructed of a 316LSS probe and a 316SS instrument flange. The instrument flange is 1¼” 150# ANSI flange standard (2 3/ 8” probe has 2½” 150# flange). The Series 25D probe is double mount-supported. This Accutube is provided complete with mounting flange and weldolet and a thredolet for double mounting. The Series 25D Accutube is factory fitted with ½” FNPT connections and is shipped with mounting hardware complete. Series 25D Accutubes are available for line sizes 2” through 72”.

• High pressure / temperature insertion type flow sensor
• Gas, liquid and steam applications
• Standard sizes up to 72” pipe
• Pressure / temperature limit: 1500 PSIG Max. @ 800ºF
Accutubes
Meriam’s Accutube Flow Sensors are lab-tested and field-proven flow elements perfect for gas, liquid or steam service. With thousands in use worldwide, the Accutube continues to be the right choice when ease of installation, cost effective operation and highly accurate performance is required.

The Accutube averaging Pitot tube is a head type device, which generates a differential pressure signal similar to the orifice, venturi, flow nozzle, and other head producing primary elements. It can be used for flow measurement only or with static pressure and temperature transmitters as the primary measurement source for a flow control loop. It has been proven that the Accutube’s flow measurement accuracy is better than that of the orifice. The Accutube also generates considerable cost savings with its simple installation and wear-free, energy-efficient design, providing a viable alternative to traditional flow measurement devices.
