Pressure Gauge is an instrument for measuring the condition of a fluid (liquid or gas) that is specified by the force that the fluid would exert.
Size: 2 1/2", 4", 6"
Pressure Range: 0.5 to 1000kgf/cm²
Working Pressure: 75% of dial range
Working Temperature: -20°C ~ 80°C
Rotameter is simple industrial flow meters that measure the flow rate of liquid or gas in a closed tube. Rotameters are popular because they have linear scales, a relatively large measurement range, low pressure drop, and are simple to install and maintain.
