  For 1/8"- 2" Pipe Sizes
Style B
Ideal for accurately monitoring pump performance and media flows through hydraulic circuits and sub-circuits
CHOICE OF THREE MATERIALS OF CONSTRUCTION
Select from aluminum, brass or stainless steel to meet system and media compatibility requirements.
UNRESTRICTED MOUNTING
Allows the designer to install the meter in any orientation – horizontal, vertical or inverted.
SUPERIOR EXTERIOR DESIGN
Weather-tight for use outdoors and/or on systems where wash downs are required.
GOOD VISCOSITY STABILITY
A sharp-edged stainless steel orifice provides excellent measurement stability for viscosities from 0-500 SSU.
RUGGED AND RELIABLE
Designed as a hydraulic service tool, this meter will provide years of maintenance-free performance.
HIGH PRESSURE OPERATION
The magnetically coupled follower and rigid pressure vessel design allows operation to 6000 PSIG and use with opaque liquids.
24 DIFFERENT PORTS AVAILABLE
Standard selection of NPT, SAE and BSP ports reduces the amount of adapters required for installation.
LOW COST ACCURACY
± 2.5% of range accuracy in center third of scale; ±4% in upper and lower thirds.
BI-DIRECTIONAL AND REVERSE FLOW OPTION OFFERED
Basic in-line liquid flow rate meters are also available in bi-directional and reverse flow versions. Click here for more information.
