Standard type purgemeter for measuring liquids andgases

P-100
Purgemeter■ OUTLINE
P-100 is a standard type purgemeter suitable for measuring both liquids and gases, covering a wide
range from built-in use for equipment to purging industrial processes, and is widely used in variousindustries. PTFE packing is available.

Although other ﬂow rate speciﬁcations are available, some ﬂow ranges need to be changed.
Contact us for details.
Low pressure loss type of production and I are available. Contact us for details.
Pressure loss of liquid, please contact.
☆ 1：It becomes the pressure loss during the valve fully open
☆ 2：For ﬂow rates of less than 150 mL/min (nor), models with the alarm code E are not available.
☆ 3：For purgemeters with PTFE gasket for ﬂow rates of less than 1 L/min (nor), models with a valve
are not available.
☆ 4：For ﬂow rates over 1 L/min, rangeability will be 10：2
☆ 5：The viscosity of the liquid will be produced Allowed only 1.0 mPa · s☆ 6：For ﬂow rates over 10 L/min(nor), rangeability will be 10：2

■ OTHER AVAILABLE OPTIONS
You can specify the following options:length of reed switch lead wire, double graduations (depending on specifications;contact us for details), special graduations, built-in check valve type, built-in valve
lock mechanism type, rubber joint type, other joint types, etc. For details, refer to"Index & Quick Reference for P Series Purgemeters" (TG-S0001).
