G1/4 Flush type Pressure Transmitter
VFM series1MPa–20MPa
- Small design (G1/4 thread)
- Suitable for measurement of viscous media since the flush type (no feed port) wetted part is hardly clogged up.
- Wetted part constructed integral with diaphragm does not use any sealed liquid, offering durability, reliability and long life.
