GAS METERS  


Drum Type Gas Meters ( Wet Type)
Series: TG

RITTER drum type gas meters are universally applicable for measuring the volume of flowing gases and are particularly effective when measurements demand the highest precision.

The possibility of selecting the gas meter material from among 5 different excellent materials (polyvinyl chloride (PVC), polypropylene (PP) polyvinylide fluoride (PVDF), PE-el (polyethylene electrically conductive) or refined stainless steel 1.4571 (316L) enables the user individually to meet measurement requirements even in case of highly aggressive gases.

For rugged, industrial applications, robust models with a stainless steel casing and plastic drum (four different materials) are available.

The desired measurement range can be selected from among 9 magnitudes (types) extending as a whole from 0.1 ltr/h to 18,000 ltr/h at a gas temperature ranging from -50 to +120oC. The solidly manufactured casing of the standard meters is designed to withstand a maximum over pressure of 50 mbar (plastic casings) or 500 mbar (stainless steel casings); meters for higher pressure ranges up to 16 bars are available.

The measurement of RITTER drum type gas meters works on the principle of displacement. The gas meters contain a revolving measuring mechanism (measuring drum) within a packing liquid (usual: water or thin bodied oil). The measuring drum compulsorily measures volume by periodically filling and emptying four rigid measuring chambers.
Fastidious production methods and calibration enable a measuring accuracy of + 0.2% at standard flow rate and approx. + 0.5% over the whole measuring range.

The major advantage and the superiority o volumetric Gas Meters (like Drum type Gas Meters) over other measurement principles, which determine gas volume using secondary measurable variables such as speed, heat capacity, hot wire resistance or similar, is that the volume is directly measured. That means that the condition and the composition of the gas has no influence on t he measurement accuracy.

Correcting factors which take into account gas type, temperature, humidity etc are therefore not necessary. It should be noted that with other, non volumetric measurement processes, the measurement accuracy given for that process can only be achieved if the correcting factors for the immediate condition of the gas are exactly known.

Bellows Type Gas Meters ( Dry Type)
Series: BG

RITTER bellows type gas meters are applicable for measuring the volume of flowing inert and dry gases and are particularly effective at high gas flows.

The desired measurement range can be selected from among 6 magnitudes (types) extending together as a whole from 40 ltr/h to 160m3/h at a gas temperature ranging from -20o to +50o Celsius. The solidly soldered casing on the standard model is designed to withstand a maximum overpressure of 50 - 500 mbar depending on the meter type.

The measure of RITTER bellows type gas meters works on the principle of displacement. The gas meters employ a twin chamber measuring unit with a deformable bellow within each chamber. Thus, a compulsory measurement of the gas flow is possible by periodically filling and emptying these chambers.

The design of the measuring chamber is such that the measuring volume per cycle of the bellows is constant Among other advantages, this design of the measuring unit enables a measuring accuracy of +/-2%.

The major advantage and the superiority of volumetric Gas Meter (like Bellows type Gas Meters) over other measurement principles, which determine gas volume using secondary measurable variables such as speed, heat capacity, hot wire resistance or similar, is that the volume is directly measured. That means that the condition and the composition of the gas has no influence on the measurement accuracy.

Correcting factors which take into account gas type, temperature, humidity etc are therefore not necessary. It should be noted that with other, non volumetric measurement processes, the measurement accuracy given for that process can only be achieved if the correcting factors for the immediate condition of the gas are exactly known.

 BG with "Totalizing Roller Counter"

   
MilliGascounter

The MilliGascounter is designed for the measurement of small amounts of gas with ultra low flow rates and is capable of measuring flow rates from 1 ml/h up to 1.2 ltr/h. It is suitable for measuring all inert and slightly aggressive gases, in particular those encountered in biogas technology or in leak rate detection.

Features:

  • Minimum flow rate 1 ml/h
  • Resolution 3 ml
  • Accuracy +3%
  • Use with inert and medium corrosive gases (biogas)
  • Material:  Plexiglass (PMMA)
  • Digital counter; battery life time 3-4 years
  • Low maintenance

The New MGC version (V3.0):

  • Is more mechanically stable
  • Less critical to flow rate overflow (with the older version the measurement cell remained in a upright position at flow rate overflow)
  • Can be used with a higher overpressure (100 mbar instead of 50 mbar)
  • Is manufactured more precisely by using a CNC drilling machine

Air and Gas Sampling Bags

Cali-5-BondTM air/gas sampling bags have been specifically designed for easy and reliable collection of air & gas samples. The non-permeable, opaque and chemically inert properties of the bags ensure that the collected gases remain uncontaminated and unaltered. 

Features:

  • Non permeable
  • Opaque - to protect collected gases against ultraviolet light
  • Do not chemically interact with gases
  • Strong enough to withstand rough and repeated handling
  • Do not become brittle or otherwise deteriorate over time
  • Simple to maintain and do not require technical training to operate
