Flow-X: Testing and Approvals

Besides the performance of the measurement hardware, the flexibility and power of the software, another key factor on usability for a flow computer includes its full conformance to internationally recognized standards and regulations.

An overview of approvals for the Flow-X series is given below.


Introduction

Since the introduction of MID in October 2006 only one approval applies for gas and liquid flow computers in all the EU and EFTA countries.

An MID approval is hence valid in 30 European countries, and forms a sound basis for additional tests and approvals in non-EU countries.

In a market where existing products sometimes have a hard time keeping up with legislation and compliance to new international metrology, we are proud to inform you that we have recently passed all MID certification tests for both gas and liquid applications without any exceptions whatsoever. 

Level A-1

Level A-2

NMi approval 2

 

Harry Kok, CEO of Spirit IT said:

Today marks a significant milestone in our company’s history and a new benchmark for the oil and gas measurement industry. In a market where the available devices have failed to keep pace with developments in modern electronics and the information technology demands of the users, Spirit IT has produced a true leading edge product that answers the markets needs for today and the flexibility for the future. Our Engineers and Partners have delivered a truly remarkable product from its unrivaled analog accuracy to its unmatched digital signal processing features, storage and software flexibility. I herewith thank all those involved in the development and our customers who’s encouragement and feedback have brought us to this remarkable point."
