Ryutai Kogyo PGH, GPB, GPC & AMF Purge and Panel Flowmeters
The Ryutai Kogyo PGH is a compact glass-tube variable-area flowmeter for small liquid and gas flows. Panel mounting suits laboratory equipment and test systems.
Compare PGH with the GPB, GPC and AMF panel flowmeters to select a suitable construction and flow scale for your equipment. Each series is specified separately; they are not interchangeable model names.
Compare the Series
| Series | Tube | Standard connection | Selection focus |
|---|---|---|---|
| PGH | Glass | Rc ¼ | Small flows |
| GPB | Glass | Rc ⅜ | Panel measurement |
| GPC | Glass | Rc ½ | Higher flows than GPB |
| AMF | Acrylic | Rc ⅜ | Lightweight panel installation |
Water Flow Range Comparison
| Series | Water-equivalent scales, L/h |
|---|---|
| PGH | Smallest 0.1–1; largest 10–100 |
| GPB | Smallest 10–100; largest 40–400 |
| GPC | Smallest 40–400; largest 120–1200 |
| AMF | 30–300; 50–500; 90–900; 120–1200 |
These are separate calibrated ranges. Select a scale for the actual fluid and operating conditions; one meter does not cover the whole series span.
PGH Features
- Direct flow indication with a 10:1 measuring range.
- Upper, lower or dual needle-valve configurations.
- Optional stand, hose nipples and constant-differential-pressure valve.
PGH Specifications
| Specification | PGH |
|---|---|
| Water-equivalent ranges | Smallest: 0.1–1 L/h; largest: 10–100 L/h |
| Air-equivalent ranges | Smallest: 2–20; largest: 250–2500 L/h (ntp) |
| Accuracy | ±5% full scale |
| Standard connections | Rc ¼-inch |
| Maximum pressure | 1 MPa gauge at 60°C; 0.6 MPa gauge at 100°C |
| Fluid temperature | 0–100°C, subject to gasket selection |
| Ambient temperature | −10–60°C |
| Body / tube | SUS304 / heat-resistant glass |
Select one calibrated range; these endpoints do not describe a single meter's span. Liquid specifications require 1.0 mPa·s viscosity. Air reference conditions are 0°C and 1 atm, with operating conditions of 20°C and 1 atm.
PGH Valve Configurations
GPB and GPC Glass Tube Panel Flowmeters
GPB and GPC use a mirror behind the tube to assist float reading. Selected configurations offer stands, needle valves, constant-differential-pressure valves and alarm outputs.
AMF Acrylic Tube Panel Flowmeter
AMF accuracy is ±5% full scale. Maximum working pressure is 0.4 MPa gauge; temperature is 0–50°C, with continuous use limited to 40°C. Alarm contacts are not available.
Preparing Your Enquiry
- Measurement: specify the fluid, minimum and normal flow, maximum flow and preferred units.
- Conditions: provide inlet and outlet pressures and operating temperature. For gases, identify the reference conditions for the flow units.
- Installation: provide the panel opening, available space, connection thread and tubing arrangement.
- Functions: explain whether you need local indication, manual adjustment or a signal to other equipment.
Seacom can compare these requirements with the individual series specifications before proposing a configuration.

Replacing a PGF Purge Meter
PGH succeeds the discontinued PGF series. Ryutai specifies mounting compatibility, but confirm the complete configuration before replacement. See the earlier PGF-N reference page.
