Primary elements
The restriction that creates the differential pressure your transmitter reads.
Flow.
Measure liquids, gases and steam with the right balance of simplicity, range and signal. Choose from local-reading rotameters, primary elements and electronic flow meters.
Rotameters
Variable-area meters. The float rides higher as flow rises, and you read the rate off a scale beside it.
Metal Tube Rotameter
For higher pressure, temperature or opaque fluids.
MTR Series
Glass Tube Rotameter
Simple local flow reading with a visible glass tube.
GTR-19
Acrylic Body Rotameter
Simple flow measurement for clean, non-corrosive service.
ABR-19 · ABR-191
Bypass Rotameter
A practical, economical option for large lines.
Orifice and bypass assembly
Meters with a digital output
For flow that has to reach a panel, a PLC or a totaliser, not just an operator's eye.
Not sure which flow meter fits?
Tell us the fluid, flow range and line size. Also mention pressure, temperature and whether the fluid is clean, dirty, opaque or carries solids. Those details usually narrow the choice quickly.
- Fluid, specific gravity and concentration
- Flow or level range, and line size
- Operating pressure and temperature
- Material of construction and end connection
- Output, display and area classification
