vortex flow meter pdf

Typical Accuracy Non. Turndown ratio is a measure of the instruments rangeability and is defined as the full-scale calibrated flow rate divided by the lowest flow rate that the instrument is capable of measuring.

Basics Of Vortex Flow Meter With Pdf What Is Piping

A flow meter that is capable of measuring flow rates ranging from 10 to 100 GPM would have a turndown ratio of 10 or 101.

. Realized in a vortex flowmeter. The generation of vortices is known as Karmans Vortices and culmination point of vortices will be approx. The scale unit of the flow meter is the flow percentage and when the lower limit range of the differential pressure is 0 we get.

A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. The differential pressure of a differential pressure flow meter is proportional to the square of the flow or the flow is proportional to the square root of the differential pressure. 075 of Reading Liquid 05 of Reading.

Expressed by the following formula. SSP accurately senses vortices in the low flow range providing outstanding flow stability. The application condition such as high vibration of the piping and pulsating flow is predicted and indicated.
