Flow
Meter with Flow Controller (Not Subject to Load Pressure Change)
MODEL
2503F SERIES
The
constant flow valve Model 2203 that permits constant flow and the
precision flow meter RK1400 are combined in this flow meter to permit
high-precision measurement and control of a wide flow range, from very
small flow to medium flow, when the pressure on the load side (outlet side)
changes.
Features
1. This flow meter ensures constant flow under constant pressure on
its inlet side even if the load pressure loss on the outlet side changes.
2. The measuring section of the flow meter is based on the
highprecision float type flow meter RK1400.
3. The precision valve permits smooth and stable control of very
small flow.
4. Constant pressure on the inlet side eliminates pressure errors of
the float type flow meter, allowing a complete flow control system to be
configured.
