6.1 General
Points to verify before meter installation:

Chemical compatibility of the liquid. Be sure that all wetted parts are
identified and confirmed suitable for use with the media being measured. If
unsure, please contact a KOBOLD engineer for guidance in obtaining the
proper reference materials.

Verify that the operational pressure and temperature limits are within
capability of the fully specified meter. Verify that the operational flow rates are
within the specified flow range. Viscous liquids may limit the maximum
allowable flow based on the viscosity. The max allowable flow rate may need
to be limited to ensure the differential pressure across the flowmeter does not
exceed 1 bar, (100 kPa, 15 PSIG).

Be sure that the flowmeter is not subject to any process temperatures and/or
pressures that can cause the measured liquid to freeze or flash inside the
meter.

the measuring instrument is not subjected to process temperatures and
pressures that convert the liquid medium into a gas inside the device.
OPERATION:
Liquid travels around the crescent
shaped chambers created by the
rotational movement of the rotors
liquid exits the
measuring chamber
liquid entering
measuring chamber
liquid in transit
