Description: The LG/LGX range of Glass Tube Flowmeters typically use the 30mm scale length borosilicate glass tube and a float. Based on the well known variable area (VA) principle of low measurement, these flowmeters provide clear, simple and reliable operation. Platon Glass Tubes from RM&C are individually scaled and calibrated according to customer's requirements. Custom scales are produced using our "Reynolds Curve" prediction software, which uses air or water calibration data corrected for the effects of temperature and pressure on the density and viscosity of the working fluid. Principle of Operation Fluid flowing vertically upwards through the tapered glass tube causes the float to rise to an equilibrium position. Flow rate is measured by reading the top edge of the float against the scaled tube. Features: Instantaneous response Simple and reliable operation Low line pressure loss High resolution Custom scales available on request SKU Fluid Type Scale Range Compatible Frame Size FRGTF1AHD-A Air 50 - 500 cm³/min 1 LG/LGX FRGTF1AHS-A Air 100 - 1000 cm³/min 1 LG/LGX FRGTF1ASS-C Water 1 - 5 l/h 1 LG/LGX FRGTF1BHD-A Air 50 - 250 cm³/min 1 LG/LGX FRGTF1CHD-A Air 5 - 100 cm³/min 1 LG/LGX FRGTF2AHD-A Air 2 - 10 l/min 2 LG/LGX FRGTF2AHS-A Air 2 - 25 l/min 2 LG/LGX FRGTF2AHS-C Water 5 - 40 l/h 2 LG/LGX FRGTF2BHD-A Air 0.5 - 5 l/min 2 LG/LGX FRGTF2BHS-C Water 5 - 15 l/h 2 LG/LGX FRGTF2CHD-A Air 0.5 - 2.5 l/min 2 LG/LGX
