Promet EExd Process Moisture Analyzers are hazardous-area rated industrial hygrometer systems for measurement of water vapor content in process gases on natural gas platforms and terminals as well as in petrochemical plants and industrial manufacturing facilities.
The Promet EExd is installed directly in the hazardous area, simplifying site installation and retrofits. Promet EExd combines proven Michell moisture sensing technologies with sample conditioning systems designed to provide a reliable and easy-to-operate, multi-channel, on-line instrument for moisture measurement in flammable gases.
Suitable for use with natural gas containing up to 20 % hydrogen with no further modification required
Applications
| Channel Configurations | Single and two channel |
| Moisture Parameters | Dew point °C and °F |
| Moisture Content | Automatic pressure compensated conversions: ppmV for natural gas and ideal gas, lb/mmscf and mg/m³ for natural gas. Dew point at a pressure input by the user for natural gas and ideal gas. Calculations for natural gas moisture content based on either ISO 18453 or IGT#8 to customer order preference. |
