Cla-Val X144D-AF-X - Manual

• The e-FlowMeter™ can be retrofitted to an existing
Cla-Val Automatic Control Valve or factory assembled
on a new valve
• Alleviates the need for an in-line meter and the
associated installation costs
• Provides flow data with accuracy +/- 2% of Full Scale
• Mounts on either inlet body tapping of the Cla-Val
Control Valve
• Stainless Steel Construction
• 4-20mA Loop Powered
The Cla-Val Model X144D-AF-X e-FlowMeter™ is a vortex
shedding insertion flow meter designed to be retrofitted into
a Cla-Val Automatic Control Valve to provide accurate flow
measurement data without the need to install a separate
meter.
The X144D-AF-X e-FlowMeter™ employs an innovative
swivel mechanism which allows the meter to be inserted
into tappings as small as 1/2-inch.

The X144D-AF-X e-FlowMeter™ uses the vortex
shedding method to measure flow. The meter is
inserted into the inlet tapping of the valve and the
measurement cylinder is oriented parallel to the
direction of flow. The flow enters the
measurement cylinder where it encounters the
bluff body, generating vortices, which in turn,
deflects off the piezoelectric sensor.
The sensor counts the vortices and
communicates the data to the meterʼs integral
circuit board. The flow data is the converted to a
4-20mA signal.
