Introduction
The XP2F is a low cost, robust, state of the art package that can accurately meter the flow through a Cla-
Val valve. To meter the flow, the XP2F assimilates data from valve mounted pressure transmitters and a
position transmitter. Using a proprietary algorithm, the flow rate through the valve is calculated and
shown on a local display. The XP2F provides 4-20mA analog outputs to retransmit the calculated flow,
measured pressures, and measured position transmitter to a nearby PLC/SCADA system. The XP2F also
logs all data to a local SD card which can be exported in CSV file format for analysis later.
The XP2F package is an ideal solution for users that need to monitor flow for control or reporting
purposes. The XP2F offers several advantages over traditional flow meter options. Because it mounts to
an existing Cla-Val valve, it’s much easier to retrofit into a system than most other flow meters (e.g. mag
meter which requires the pipeline to be cut for installation). Additionally, there is minimal straight pipe
upstream or downstream requirements for the XP2F to accurately meter flow.
In the standard setup, the XP2F package consists of an upstream and downstream pressure transmitter,
a valve position transmitter, and a calculation module as depicted in
Figure 1.1
The XP2F package can be customized with different components. The upstream and downstream
pressure transmitters can be substituted with a differential pressure transmitter. Additionally, the XP2F
comes standard with a Cla-Val X117H position transmitter (as shown in
) but can be used with
a Cla-Val X117D position transmitter as well.
