SECTION 4.0: START-UP & COMMISSIONING FOR GREYLINE
INSERTION ELECTROMAGNETIC FLOW METERS
A step-by-step procedure and companion worksheet are located on the next two pages. Please
read all installation instructions carefully before proceeding with installation, start-up and
commissioning.
Please read these helpful hints before proceeding with the start-up and commissioning procedure
on the next page.
1.
GREYLINE flow meters are individually calibrated for a particular application.
Be sure to verify the pipe size and location.
2.
The electronic flow sensing systems will not work in air.
3.
When measuring analog output signals, remember that current (mA) must be
measured in series, while voltage is measured in parallel. If the 4-20 mA signal
is already connected to a control system, you must break the connection and
measure the signal in series.
4.
When measuring frequency outputs in Hz, take your multimeter out of “autorange
mode” and manually set the range for a voltage level above 15 VDC. This will
prevent false readings when signal is not present.
5.
All wiring connections should be made at the end of the factory cable. Do not
attempt to remove the factory installed cable or change the orientation of the
electronics enclosure.
6.
Never connect power to analog or frequency output signal wires. GREYLINE ISM
5.0 Flow meters are not “loop powered” devices.
