On-line infrared gas calorific value

The detailed information

Scope of application:

Suitable for coalbed methane, gas composition and calorific value.

Technical indicators:

Measurements: the concentration of CH4 and CnHm, gas calorific value

Measurement: the CH4 and CnHm: NDIR nondispersive infrared

Quantity: cheng CH4:0 ~ 100% CnHm: 0 ~ 10%

Resolution: CH4 and CnHm: 0.01%

Fine degrees: CH4 and CnHm: plus or minus 1% or less of FS

Repeatability error: CH4 and CnHm: 1% or less

The best flow: 0.7 ~ 1.2 L/min

Inlet pressure: 2 kpa ~ 50 kpa

Sample gas requirements: clean, no water, no oil
