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.
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
