美国 Meriam33T系列低压型湿塔安装Accutube流量传感器的详细介绍
Series 33T Low Pressure Accutube Probe And Wet Tap Mounting Assemblies.
Series 33T Accutube Probe And Wet Tap Mounting Assemblies. Use of the 33T allows insertion and removal without process shutdown. The 33T probe consists of a standard brass head and a 316SS probe and installs through a wet tap assembly. The wet tap assembly consists of a packing gland, pipe nipple, insertion valve and thredolet or pipe saddle clamp. The 33T has 1/ 8” FNPT connections and is shipped with wet tap assembly and safety chain.

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.
Confidence
• Testing by the Utah Research Laboratory-Utah State University, the University of Michigan and testing against NIST traceable Meriam flow elements confirm typical accuracy of ±1% of rate
• Material Certification and Certificate of Conformance per customer specification are available
• Certified welding fabrication to ASME Code, Section IX Procedures.
• Dye penetrant and hydrostatic testing capability
• Canadian registration number
Convenience
• Applicable to gases, liquids, steam
• Simple installation and maintenance
• Four standard models and probe sizes: Insertion, Flanged, Wet tap with socket or gear drive retraction, Integral three-valve manifold, optional
• Bi-directional flow sensing
Efficiency
• Low permanent head loss saves energy and cost
• Multiple tube design offers superior strength and clog resistance
• Unaffected by wear
• No system shutdown with wet tap model
• Ideal for flow system upgrades and expansions
• Integral 3-Valve head option saves installation piping and transmitter mounting time
• Gear Drive wet tap reduces insertion and retraction time
