Dry Flowmeters

Reference Flowmeters

The most commonly used flowmeter is the orifice meter. The orifice meter consists of two parts. As shown in Figure 1, they are the measurement orifice plate, which is installed in the process line, and the differential pressure transmitter, which measures the pressure developed across the orifice plate. There has been extensive research to determine the operating characteristics of orifice meters.

Cross Correlation Flowmeters with Ae Sensors

This paper is concerned on the new type of the sensing elements for a particle volume of flow rate measurements based on cross correlation flowmeters. The new type of sensing elements exploit the fact that the solid particles being carried by a flowing air and impacting a properly formed obstacle generate an acoustic surface wave (acoustic emission AE). The acoustic signal is indicated by the a...

A New Approach to Laminar Flowmeters

After studying the performance and characteristics of actual laminar flowmeters a new disposition for this type of sensors is proposed in such a way that the measurement errors introduced by the intrinsic nature of the device can be minimized. The preliminary study shows that the developing entry region introduces non-linearity effects in all these devices. These effects bring about not only er...
