Packing Fluid & Level Indicator

Suitable for all Drum-Type Gas Meters

Pioneer 4281 Silox CalRiX

Pionier 4281 is a medical paraffinic mineral White Oil containing aromates in trace elements. It is colourless, odourless, and clear.

Available in 5ltr canister

Silox is a synthetic oil belonging to the group of polydimethyl siloxane. It is colourless and clear with a weak odour.

The use of Silox is recommended when the gas should remain dry or when the gas reacts with water.

Not suitable for wet chlorine gas and butane.

Available in 200ml, 500ml, 1ltr & 5ltr

CalRiX is a completely synthetic fluid on a fluorine base. It is of low molecular weight, colourless, clear and odourless.

Because CalRiX is completely inert to most gases including oxygen, it can be used as a Packing Fluid when water or paraffin oil are not suitable. For example, when the gas needs to remain dry, and when the gas is highly reactive to water or paraffin oil.

Available in 1ltr

Advantages:

  • Use under 0°C.
  • Less evaporation than water due to its lower vapour pressure.
  • Greater stability of the Packing Fluid level.
  • Improvement in the repeatability of measurement results.
  • Reduction in the required frequency of Packing Fluid level monitoring.
  • The gas remains dry.
  • In general, a lower chemical reactivity with water.

Advantages:

  • Use under 0°C (down to -40°C)
  • Less evaporation than water due to its lower vapour pressure, resulting in greater stability of the Packing Fluid level and in more consistent measurement result
  • The gas remains dry
  • In general, a lower chemical reactivity than water

Advantages:

  • Extremely resistant even against highly aggressive gases because of CalRiX's fluorine base
  • Less evaporation than water due to its lower vapour pressure, resulting in greater stability of the Packing Fluid level and in more consistent measurement result
  • Very smooth rotation of the measuring drum in the Gas Meter because of CalRiX's high density and low surface tension.

High Precision Packing Liquid Level Indicator

The High-Precision Packing Liquid Level Indicator allows highly precise reading and setting of the packing liquid level in RITTER Drum-type Gas Meters. Precise adherence to the factory-set level is very important for the Meter's measuring accuracy, as the measurement deviation given in the Calibration Certificate is only valid when the packing liquid level is correct. Packing liquid levels other than that set in the factory cause the volume in the chambers of the measuring drum to be different to the volume at time of calibration, which inevitably results in a measurement error.

Operational principle

The High Precision Packing Liquid Level Indicator consists of the following parts:

Following the principle of communicating pipes, the sloping tube is connected with the packing liquid in the Gas Meter casing. Because of this, the liquid level in the sloping tube exactly reflects the level in the Gas Meter casing. Because the tube is sloping i.e. set at a small angle to horizontal, a small change in the liquid level in the Gas Meter casing results in a large change in the liquid level inside the sloping tube. Thus, the sloping tube acts like a magnifier of the liquid level inside the casing and can therefore be set extremely precisely. Furthermore, parallax error when reading the level, as can occur with the Standard Level Indicator, is nearly impossible.
