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.
The Accutube is an annular averaging Pitot device, which is simply inserted into a pipe or duct through a weld coupling and packing. Based on pipe or duct size, the Accutube is constructed so that strategically located sensing ports continually sample the impact and static pressures produced by the Accutube’s obstruction of the flow stream profile. Within the probe, the impact pressures sensed by the upstream ports are continually averaged in an isolated plenum chamber. Similarly, the static pressures sensed by the downstream ports are averaged in a second isolated plenum. A readout device is then used to indicate the differential between the two-plenum chambers.
Meriam Accutubes are provided in a wide variety of models enabling you to select the probe diameter and mounting configuration compatible with your application needs. Meriam also has available special mounting hardware, valves and materials for use in high temperature and pressure applications and corrosive environments.
