FAQ
What is a meter proving actuator?
A meter proving actuator operates the valve used in a meter proving application. Meter proving is used to verify the accuracy of meters measuring product that moves through a pipeline, making reliable actuator operation an important part of the measurement process.
Why is actuator speed important in meter proving applications?
Meter proving actuators operate at high speed and may cycle many times per day. Changes in actuator cycle time can affect the operation of the proving process and may indicate that something in the valve or actuator system has changed.
What can cause a change in Rotork actuator cycle time?
A change in valve gearing can affect actuator cycle time. In a recent meter proving application, Power Controls determined that a gearing change was responsible for increased cycle times.
Can a Rotork actuator's onboard datalogger support predictive maintenance?
Yes. The onboard datalogger can provide operating information that can be monitored over time. This data can help operators identify changes in actuator performance and take a more proactive approach to maintenance.
Does Power Controls support Rotork actuators in meter proving applications?
Power Controls provides field support for Rotork actuator applications, including troubleshooting and diagnostic support for high-cycle applications such as meter proving.
Can wiring issues on a Rotork IQ3 actuator be diagnosed without external test equipment?
Yes. The Rotork IQ3 includes built in on screen status features that can help identify incorrect wiring terminations directly through the actuator.
Can incoming control signals be verified through a Rotork IQ3 actuator?
Yes. The IQ3’s on screen status features can be used to verify incoming control signals without using an external meter or other test equipment.
What is manual setup mode on a Rotork IQ3 actuator?
Manual setup mode allows the actuator to be configured locally using the control knobs and screen at the actuator.
Can Rotork IQ3 actuators be configured for failsafe applications?
Specific IQ3 actuators can be equipped with an internal lithium ion battery for a customer specified failsafe application.
Does Power Controls provide Rotork actuator commissioning support?
Yes. Power Controls provides technical and field support for actuator applications, including commissioning, troubleshooting, configuration, and diagnostic support.
