Instrotech showcases range flow meters

April 5, 2016  1062  1062 Bookmark   

KOBOLD Instrumentation, represented in South Africa by Instrotech – a Comtest Group company – has a range of mechanical flow meters comprising of the KSK & KSM models, for high-volume measurement and the KFR model specifically for low-flow volumes.

The model KSK plastic flow meters and switches are based on the proven suspended float principle for measuring and monitoring flows in closed pipes. The media flows from below through a conical plastic measuring tube, which raises the float, and the flow rate can be read off against the scale. They are shock- and corrosion-resistant and can be inserted or removed radially. Measurement parameters are:

  • Water 1.5 – 11 to 100 - 1000L/h
  • Air 0.15 – 0.45 to 20 - 105m3N/h
  • Accuracy - category 4 (According to VDE/VDI 3513 Sheet 2)
  • Material: Trogamide, polysulfone, PVDF

The model KSM is also based on the float principle with the float moving freely without friction in the measuring tube. In this model the indication point is at the greatest diameter of the float. The standard flow meters are supplied with a scale for water (+20ºC), a percentage scale, o-rings, two set point indicators and a guide rail for accessories. The measuring tube is available in various housings for aggressive media and is resistant to impact, bending and compressive stresses. Measurement parameters are:

  • Water 15 – 150 to 8000 – 60 000 L/h
  • Air 0.8 – 5 to 300 - 2500m3N/h
  • Accuracy + 4% of full scale
  • Material: Trogamide-T, polysulfone, PVDF

Applications for this model include cooling circuits, water treatment and plant engineering.

The KOLBOLD low volume flow meter model KFR is constructed as a single unit, that is, it has an acrylic housing with removable PVC, brass or stainless steel connections and finds application primarily for gas analysis and most water applications. Measurement parameters are:

  • Water 5 – 50cm3 /min 5 - 75 L/min
  • Air 0.05 – 0,5 L/min to 400 – 4 500 L/min
  • Accuracy + 2% to 5% of full scale
  • Material: Acrylic
