Volumetric flow rate sensors
SCVF volume counter
Gear counter for highly accurate flow rate
measurements in hydraulic systems
Function
The SCVF geared counter functions as a volume flow me-
ter. A very precisely crafted pair of geared wheels is driven
by the fluid flow.
The SCVF works over a wide viscosity range. Different
seals permit usage in many different applications.
Applications
Due to the wide viscosity range, any liquid can be meas-
ured that can be pumped and has a certain degree of
lubricating capability.
Brake fluid (EPDM seal)
Skydrol
Mineral oils
Hydraulic oil and
Grease
The SCVF is the ideal solution when carrying out precise
flow rate measurements over a wide viscosity range.
