Safe Use Instructions – MVS205
Set the address of each MVS prior to final
wiring of multiple MVS devices. For proper
operation of multiple MVS devices, each MVS
device must have a unique address. The
FloBoss 407 allows up to four MVS devices;
ROC306s and ROC312s allow up to three
devices; ROC364s allow up to five devices; and
ROC800-Series allows six devices per module,
and up to two modules per ROC800-Series.
Connect the ROC/FloBoss to a computer
running ROCLINK 800 software.
Select Configure > I/O > MVS Sensor.
Navigate to the MVS screen associated with
the MVS being addressed.
Enter the unique number in the Address
field. Do not use addresses 0 or 240.
Click Apply or Save to save your changes.

Use Sealtite
(or a similar product) to seal
the conduit path from the Remote MVS to the
ROC or FloBoss. Unarmored cable may be
used if installed in conduit and have seals per
hazardous installation practices. Before you
calibrate and place the MVS205 sensor into
operation you must configure it using ROCLINK
800 software, which runs on a personal
computer (PC). The PC is normally connected
to the LOI port of the flow computer to transfer
configuration data into the MVS205 sensor.
Default values for all parameters exist in the
firmware of the MVS sensor. If the default is
acceptable for your application, it can be left as
it is. Perform any adjustments to the MVS unit
through the ROC or FloBoss configuration.
Refer to the ROCLINK 800 Configuration
Software User Manual (Form A6121).
If the MVS205 sensor is to be used in bi-
directional flow conditions, refer to the
ROC/FloBoss Accessories Manual (Form
A4637) for configuration details.

The calibration routines support 5-point
calibration, with the three mid-points calibrated
in any order. Calibrate the low-end or zero
reading first, followed by the high-end or full-
scale reading. Calibrate the three mid-points
next, if desired. For the calibration procedure,
refer to the ROCLINK 800 Configuration
Software User Manual (Form A6121).
11.
Once the end caps are in place and the
cover clamps have been slipped over the end
caps and tightened into place, the MVS205
sensor can be placed into operation.
12.
To troubleshoot problems with the MVS205
sensor, identify whether the problem is with the
configuration or the hardware. Check the
configuration in ROCLINK 800 software to
identify any incorrect settings. Inspect the
hardware for damage. Inspect the circuit board
for connection location errors.
If these methods do not solve the problem,
contact your local sales office.
13.
During operation, the MVS205 sensor can
be monitored locally or remotely. For local
monitoring, use ROCLINK 800 software on a PC
connected through the LOI port. For remote
monitoring, a host must poll the ROC or FloBoss
attached to the MVS205 sensor.
14.
To remove the MVS205 sensor from
operation, disconnect power from the unit and
then remove all external wiring connections.
Isolate the unit from the process gas and vent
the connection lines.
15.
Finally, remove the sensor from the
pipestand or orifice plate and place it in a box
for transportation.
