Description
The ST100A belongs to the high performance thermal dispersion meters and measures gas mass flow directly, without conversion by pressure and temperature. It uses Adaptive Sensing Technology (AST) and advanced flow sensors for industrial processes and plant applications. The Ex d housing withstands an explosion inside, so the instrument goes into zones with explosive gases, and Ta from -40°C to 65°C sets the ambient operating range. IP67 protects against dust and temporary immersion. The approval list is long, from ATEX and IECEx to NEPSI, CRN, Inmetro, UKCA and CE, plus FM/CSA for Class 1 Division 1. The electronics offer a rich set of functions, so setup and diagnostics are done on site.
How to choose
What decides the choice is the certification the site demands. For Europe and countries accepting IECEx, look at the ATEX and IECEx entries, for North America FM/CSA with Class 1 Division 1, and for dust zones Groups E, F, G. If explosion protection is not needed, consider other models of the ST series.

FAQ
What ambient range does the ST100A have in explosion-protected form?
For the IECEx version Ta is listed from -40°C to 65°C.
What protection rating does the ST100A housing have?
IP67, meaning the housing is dust-tight and withstands temporary immersion.
What explosion-protection approvals does the ST100A hold?
ATEX (Ex d), IECEx and FM/CSA Class 1 Division 1 Groups A, B, C, D; for dust Groups E, F, G.
What does Adaptive Sensing Technology do?
An advanced flow sensor technology that the maker uses in the ST100A for industrial processes and plant applications.
