​First Center-tap Flow Measurement Device

HOUSTON, TX (June 6, 2017) – Bell Technologies, LLC introduces the CENTER-TAP TORUS (CTT) – a flow measurement device that delivers accurate and quantifiable measurement of multi-phase drilling fluids.


A primary flow element with a maximum pressure rating of 20,000 psi, the CTT is designed to handle the higher flow rates and multi-phase fluids that are typical in the drilling industry.  By tapping the center of the device throat, the primary element produces a single averaged pressure point from multiple points to equal the most accurate volume on any combination of flows. The location of the sensors is the key to obtaining the one pressure on a 360-degree circle. Learn more

Bell Technologies Receives Patent for Innovative New DP Flow Measurement Element


Houston, TX ( -- Bell Technologies announced today that it has received a patent for the TORUSWEDGE™ primary flow element. The patent gives Bell its eighth patent for differential pressure flow measurement products and solutions.

"The patent was awarded based on the unique design of a two-sided sealing flange and the entrance and exit ramps performance over all other differential pressure devices," said Dave Bell, Owner, and the technology's creator. We believe the TORUSWEDGE flow element will revolutionize differential pressure measurement well into the next century." ​

The patented TORUSWEDGE primary flow element design incorporates an innovative circumferential wedge which completely encircles the flow stream. This unique wedge element combines the qualities of the orifice plate with the durability of the wedge. The result is a meter offering the highest accuracy and durability of any type of wedge meter.
