Frequency Measurement

The X144D 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 meter’s integral circuit board. The flow data signal is converted to 4-20mA, or transistor (NPN) pulse, depending on the desired application.

The Cla-Val Model X144D 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.

Configured for installation in the inlet tapping of a Cla-Val Automatic Control Valve, the X144D can be used in valves directly downstream of a flow disturbance such as elbows, valves or a reducer. (See page 2 for installation guidelines)

The X144D e-FlowMeter employs an innovative swivel mechanism which allows the meter to be inserted into tappings as small as 1/2-inch. For applications involving installation in close proximity to pump discharge, please consult factory with details.

Installation Guidelines and Typical Applications

Installation Locations

For optimum performance, it is recommended that the valve in which the X144D e-FlowMeter is installed be located as shown below.

Typical Applications

The X144D e-FlowMeter is ideal for installation in any application where metering is desired. Combining additonal Cla-Val electronic products with the X144D e-FlowMeter provides even more access to valve performance data installed in remote locations.

Data Acquisition and Storage using Cla-Val Power Generator

The X144D e-FlowMeter connects to most commercially available loggers with the choice of 4-20mA or pulse output
The VC-22D Controller and X145 e-Display are ideal companions to the X144D e-flowMeter, providing access to real-time data
The VC-22D Controller, e-Display and e FlowMeter can be powered by the X143 Series Power Generators

installation Notes:
• Consult factory for other installation configurations
• Do not use butterfly valves as isolation valves adjacent to X144D installations

of the bluff body to be parallel to upstream flow

Power Requirement

12/24 VDC, 1.0 Watts minimum

X144D e-Flow Meter Sizing

The X144D threads directly into the inlet tapping of a Cla-Val Control Valve. The size of the e-FlowMeter is dependent on the specific valve size for which it has been calibrated – no additional fittings are required. See dimension chart on previous page.

Cabling

The unit is supplied with 30 feet of shielded cable.
