Series 970 Gasoline CVS System

The Signal Group Constant Volume Sampler (CVS) uses the Critical Flow Venturi (CFV) method to accurately measure the mass emissions of vehicle or engine exhaust. The CVS flow calculations are based on the current international regulations using the fluid dynamics principle associated with critical flow.

Series 970 Gasoline CVS System

The complete CVS system comprises an Ambient Air Filter Module (3 stage), mixing tee and ambient bag sample point. Also a CVS Sampler Rack containing a cyclone separator, heat exchanger and water recirculation system.  A main CVF, dilute bag sample point and CVF, and a dilute continuous sample point. It also contains temperature and pressure transmitters.
A CVS Bag Control Rack containing a sampling system for gas path to and from the sample bags, sample pumps, filters and flow control and 8 sample bags and hanging frame.  Turbine exhaust unit and starter module.

Benefits

  • 1 phase for motorcycles
  • 3 or 4 phase for vehicles (6 or 8 Bags)
  • Multiple CFV option
  • Compact, modular design

Heated Sample Lines

1/4" &  3/8" tube diameter, 1m to 20m in length. Signal Trace Heated Line is designed to convey hot exhaust gasses from sample  points and probes  to analyser, without  compromising sample integrity.

With   safety a major consideration the tough,   flexible line is electrically isolated from  the main supply and is thermally insulated  to allow handling even at full temperature.

Heated Sample Lines

Key Benefits:

  • 1/4" or 3/8" OD
  • Lengths from 1m to 20m
  • Available with replaceable PTFE lines
  • Braided heating element eliminates cold spots


Applications:

  • Vital for accurate testing of heated samples containing soluble or condensing gases.

EMIRAK Integrated Automated Measuring System

The Emirak has been purpose designed for compliance to EN14181. It is available for standard pollutants NOx, CO, SO2, THC, HCl, HF and ust with oxygen and moisture measurement and compensation built in.  It is supplied with a full suite of compliance software to make easy work of QAL 3 requirements.

EMIRAK Integrated Automated Measuring System MCERTS approved

Emirak is an extractive multigas analyser system for continuous emissions monitoring.  It is normally used to measure the concentration of NOx, SO2, CO2, O2, hydrocarbons (HCs) and water vapour in the flue gas of large combustion processes, incinerators and other processes when it is required by legislation.

Key Benefits:

  • MCERTS approved compliant with EN15267-3
  • User friendly computer driven interface
  • Easy to maintain with automatic calibration
  • Control, logging, report and alarm functions
  • Wide choice of enclosures - mobile vans, cabins


Applications:

  • Environmental  compliance
