Series 24D/25D Flange Mount Accutube

Series 24D Accutube - Single Mount. The Accutube Series 24D Standard Probe is constructed of a 316LSS probe and a 316SS flange. The instrument flange is 1¼” 150# ANSI flange standard (2 3/8” probe has 2½” 150# flange.) The Series 24D probe is single-mount supported and installs through a carbon steel mounting flange and
weldolet. The Series 24D Accutube is factory-fitted with ½” FNPT connections and is shipped with mounting hardware complete. Series 24D 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.
