CAMASS® calibration lab

Exact Calibration - Simulation of the real operating conditions

When using technologically sophisticated systems to measure and conrol gas flow as well as aeration air, calibration becomes the decisive factor for success. In order to ensure optimum measuring and control accuracy, each VACOMASS® and COMBIMASS® flow meter is precisely calibrated in the CAMASS® Calibration Centre under real operating conditions.

  • Calibration takes place taking into account the installation situation, the inflow, pressure and temperature in a closed calibration loop in the Binder calibration center or in an external DAkkS-accredited test laboratory according to DIN ISO 17025
  • Comparison is made against standards
  • On-site piping can be simulated by installation of up to 12 m original piping into the calibration loop

In contrast to liquid media, the properties of gases far more depend on the operating conditions, the gas composition and the actual flow conditions in the pipeline. If such parameters are not taken into account, considerable limitations with regard to the measuring accuracy have to be accepted.
The VACOMASS® calibration module is the coordination and integration of all individual components under simulation of the real system plant in the CAMASS® calibration technical center:

6 Calibration levels are possible

Level 1:
If sufficient straight inlet and outlet pipe sections are available, the VACOMASS® flow meter receives the system-specific standard calibration as a single flow meter. The process conditions such as installation situation, pipe orientation, flow rate, pressure temperature are taken into considerations.

Level 2:
If available straight inlet and outlet pipe run is short and if the air flow meter is placed closely in front of a VACOMASS® control valve, both components as a compact unit put into the calibration loop. Flow meter is calibrated at different strokes of the valve. The stroke compensation can be processed in the electronic cabinet VACOMASS® flexcontrol or directly in the enclosure of the flow meter AL/ SS100.

Level 3:
If straight pipe run is extremely short, VACOMASS® air flow meter is calibrated considering stroke of the valve and original pipe run, that is replicated on a scale of 1: 1 and installed in the CAMASS® Calibration Lab.

Level 4:
Ist mit Pulsationen zu rechnen, wird der VACOMASS® flow meter zusätzlich direkt nach einem Strömungsgleichrichter er eingebaut. Die Kalibrierung erfolgt als kompakte Einheit.

Level 5:
The calibration is carried out according to criteria to be determined before at an external DAkkS-accredited test bench with measuring equipment that are regularly traceably checked and compared by the PTB.

Level 6:
in big pipes, if the installation conditions are very cramped and there is not sufficient straight inlet and outlet pipe run, measuring accuracy can be increased using a multi-point sensor system. The VACOMASS® flow meter multi is calibrated according to the project and application.

  • Digester gas
  • exhaust air
  • All techincal gases and gas mixtures

VACOMASS® flow meter

The VACOMASS® air flow meters use thermal mass flow principle and measure the gas mass flow respectively standard volume flow directly, independent of pressure and temperature of the medium at standard conditions according to DIN 1343.

COMBIMASS® basic

The field transmitters of the COMBIMASS® series are suitable for flow rate measurement of compressed air and technical gases at medium temperatures up to 130°C. The flow transmitters apply thermal dispersion technology in order to measure in dry gases directly the normal volumentric or gas mass flow, regardless of the operating pressure and temperature of the medium. COMBIMASS(R) convert transmits all data to the main PLC using all common types of communication.

COMBIMASS® eco

The field transmitters of the COMBIMASS® eco series are suitable for gas flow measurement and cover a wide range of different applications. The flow transmitters apply thermal dispersion technology in order to measure directly in dry gases the standard volumetric or gas mass flow according to DIN1343, regardless of the operating pressure and temperature of the medium. The instruments can be employed for process temperatures up to 220°C and are available in explosion proof versions. COMBIMASS(R) convert transmits all data to the main PLC using all common types of communication.

COMBIMASS® eco

The COMBIMASS® eco is a thermal gas flow meter with a customized calibration range for sewage and landfill gas. It measures in dry gases the gas flow rate directly at standard pressure and temperature according to DIN 1343 and can be used both of gas production and consumers.

COMBIMASS® eco-bio+

Precondition for a reliable, precise and reproducable measurement of biogas is the determination of flow rate at standard conditions. All instruments of COMBIMASS® eco-bio+ series use thermal dispersion technology and determine the volumetric flow rate at standard pressure and standard temperature directly. Waterdamp portion must be compensated only, to measure flow rate at standard conditions according to DIN 1343.

COMBIMASS® multi

A COMBIMASS® multipoint system allows precise measurements of flow rate of pressurized air and technical gases even with short inlet and outlet pipe sections, nominal diameters larger than DN 500 or rectangular ducts. In such situations flow profile distortions may occur, which normally lead to errors in flow metering of gases.

COMBIMASS® AL100 / SS100

The field transmitters COMBIMASS® AL100/ SS100 are suitable for flow rate measurement of compressed air and technical gases at medium temperatures up to 130°C. The flow transmitters apply thermal dispersion technology in order to measure directly in dry gases the normal volumentric or gas mass flow, regardless of the operating pressure and temperature of the medium (DIN1343). Additional signal inputs and outputs can be used for simultaneous correction of signals, if flow profile or gas composition change during operation. COMBIMASS® convert transmits all data to the main PLC using all common types of communication.

COMBIMASS® syngas

Das Messsystem COMBIMASS® syngas ist eine Gerätekombination in Zwischenflanschausführung und besteht aus zwei Sensoren: einem Wärmeleitfähigkeitssensor in der strömungsberuhigten Zone und einem thermischen Sensor im Gasstrom. Der Wärmeleitfähigkeitssensor ermittelt näherungsweise die sich ändernde H2-Konzentration im Gas und korrigiert das Messsignal des thermischen Sensors entsprechend.
