Dew point transducer
CONG Prima-2M can be configured for direct installation on the pipeline
Pipeline installation can be outfitted with a filtration module
The CONG Prima-2M dew point transducer is an automatic condensation
hygrometer designed to measure the water dew point and hydrocarbon
condensation temperature of natural gas at preparation, transportation and distribution facilities.

Sample conditioning system
The analyzer is supplied with a simple sample conditioning system. Sample conditioning system consists of:
- 4 x 2-way valves
- filter/liquid block
- heated pressure regulator
- regulator to safe pressure release
- 2 x pressure gauge
- 2 x flow indicator high pressure
- small panel
Advantages:
Proven design, this technology is used by GERG as the standard instrument for hydrocarbons measurement!
• Continuous flow
• Very low power consumption max 15W
• Small footprint
• Standard warranty 18 / 24 month
• Build in supplemental cooling possible
• Highly robust and reliable, non-metallic transparent mirror, all wetted parts in 316L, specially coated for acetic gasses available
• Safety: ExD enclosure without flammable pressurized gas
Electronic and wetted parts are separated. No pressure build-up inside enclosure possible, no safety flow shut off needed.
• Quantification of hydrocarbons liquid in gas possible. Comparable to gravimetric measurement.
