Key parameters
Accuracy
+/-5% of full scale
Type
Stainless steel tube variable-area flowmeter / rotameter (7100 Series)
Metering Tube
316L SS
Internals
316L SS and Hastelloy C-276
Flow Water
0.6 to 25 GPH (2.4 to 95 LPH)
Flow Air
1 to 120 SCFH (28.3 to 3400 SLPH)
Fits low-flow stainless variable-area metering where you need a King 7100 Series 316L tube rotameter covering about 0.6–25 GPH water or 1–120 SCFH air with ±5% of full scale accuracy.
Key advantages
- Tube / internals — 316L SS tube; 316L SS and Hastelloy C-276 internals
- Flow — Water 0.6–25 GPH (2.4–95 LPH); air 1–120 SCFH (28.3–3400 SLPH)
- Accuracy / turndown — ±5% FS; repeatability 1%; 10:1 turndown
- Pressure — Valve models 1500 psig; non-valve 4000 psig (FNPT)
- Connections — 1/4 in FNPT horizontal; 1/2 & 1 in 150#/300# flanges vertical
Typical applications
- Low liquid/gas flow indication.
- Panel and process VA metering.
- Corrosive service with Hastelloy internals.
Selection guide
- Media / scale — Water vs air (or liquid SG)
- Valve vs non-valve — Pressure class
- Orientation — Horizontal FNPT vs vertical flange
- Ambient — −40 to 125 °F
Common mistakes
- Using liquid scale for gas without conversion.
- Exceeding valve-model 1500 psig limit.
- Wrong mounting orientation vs connection style.
When to RFQ / what to tell us
- Media, flow, P, T, connection.
- Valve yes/no; quantity; ship-to.
