Flow meter gas vemmtec

Deskripsi

Sizes, Flow Rate and Flanges Flow meter gas vemmtec
The available nominal diameter of the IGTM gas turbine
meter ranges from 50 mm (2″) to 400 mm (16″). Other
sizes are available on request.
The IGTM can be delivered with G rates ranging from G40
to G4000, which means that IGTMs are available for flow
rates from 10 m3/h to 10 000 m3/h.
The relationship between G value and flow rate for each
diameter is shown in table 3 on the last page of this brochure.
Carbon steel or stainless steel IGTMs can be manufactured
either with ANSI flanges or with DIN flanges in the ranges:
ANSI 150RF – ANSI 600RF
PN 10 – PN 100
Ductile Iron (EN-GJS-400-18-LT; GGG 40) meter bodies are
available in diameters from 50 mm (2″) to 200 mm (8″) and
pressure class PN10 – PN16 and ANSI 125RF – ANSI 150RF

Accuracy Flow meter gas vemmtec
Standard accuracy limits for CT-models are in accordance
with the EC directives and many foreign regulations:
± 1% for 0.2 Qmax to Qmax
± 2% for Qmin to 0.2 Qmax
As an option for the CT model the accuracy limits can be
improved to:
± 0.5% for 0.2 Qmax to Qmax
± 1% for Qmin to 0.2 Qmax
These limits are valid for the meter performance in ambient
air. Usually, the performance is better at high-pressure applications.
On request we can offer meters according to your accuracy
specification.
The repeatability of the vemm tec IGTM is better than 0.1%
Typical performance curves at different pressures are shown
in picture 1.
