Details

Description

The flow element consists of a body and wedge flow restriction. This restriction creates a differential pressure in proportion to the square of the volumetric flow rate. The wedge restriction has no critical surface dimensions, or sharp edges, that will affect measurement accuracy as the result of normally expected wear.

Advantages

■ Bi-directional flow
■ High accuracy ±0.5 % of actual flow rate
■ Low reynolds number measurement, Rd500
■ Minimum upstream and downstream pipe measurement

Specification

Measuring fluid	Liquid, Gas and steam
Material	304SS, 316SS, 316L SS and Carbon steel Special materials are available
Pipe size	0.5" ~ 24"
Wedge element standard H/D ratios	0.2, 0.3, 0.4, 0.5, 0.6 and 0.7
Accuracy	● Calibrated 1" or larger : ±0.5 % of actual flow when operated within the calibrated range 0.5" : ±0.75 % of actual flow when operated within the calibrated range ● Uncalibrated : ±5 % of actual flow when using nominal Kd²from sizing program. Applies to bi-directional flow ● Bi-directional : Same as above when Kd² designated as reverse flow coefficient
Repeatability	±0.2 %
Rangeability	10:1
