1. Pressure ratings are based on static pressure applicable at
250°F.
2. Glass tubes are not usable for caustic service.
3. Fluid temperatures below 32°F will cause frosting of the glass
metering tube. Please consult factory for applications below
this temperature.

Spherical
-
Lowest meter capacity and
no viscous fluids with medium
capacity.
Type LJ
-
Maximum flowmeter capacity
with limited viscosity
immunity.

Type RV (rib guided)
-
Highest immunity to viscous
fluids with medium meter
capacity. (Most stable)
Type GV (rod guided)
-
Analogous in design to a
sharp edge orifice. Gives
most immunity to viscosity
variations of the fluid being
metered.

Type RV
(Rib guided)
Type RS (rib guided)
- High
flow capacity with some
immunity to viscous fluids.
Type GS (rod guided)
-
Analogous in design to a flow
nozzle or venturi. Offers the
maximum flow capacity in any
given size flowmeter.
