O-180/780 Indicator integrated

General

O-180/780

O-180/780 is a series of Orifice flowmeter for liquids and gases. An orifice plate is integrated in the measuring tube and the bypassed flow is indicated by a small sized glass tube flowmeter.
The are in one piece and no additional bypass piping etc. are needed. The flow measurement in large size lines can be conducted economically. Any flow directions (horizontal and vertical) are acceptable and changing in field is also possible. There process connections of flanges, wafers and threads are available to choose.
O-180 is the indication only whereas O-780 is provided with alarm contact additionally

Recommended Applications

· Air conditioning lines (water and air)
· Water treatment lines
· Other utility lines
