1-3 Specifications
WARNING
Do not operate this instrument in excess of the specifications listed
below. Failure to heed this warning can result in serious personal
injury and/or damage to the equipment.
WARNING
Glass metering tubes are designed for operation up to the maximum
operating pressures and temperatures as specified herein. Due to
the inherent brittle characteristics of glass and conditions beyond
our control, tube breakage could result even within specified
operating conditions. Do not use glass tube meters with fluids that
are toxic, or chemically react with glass such as water above 140°F,
steam, alkalis, flourine, hydrofluoric acid, or molten metal. Failure
to heed warning can result in serious personal injury and/or damage
to the equipment.
Pressure/Temperature
200 psig at 33°F to 250°F (1°C to 121°C)
Fluid temperatures below 32°F (0°C) will cause frosting of the glass
metering tube. Consult factory for applications below this temperature.
