SECTION 1.0: INTRODUCTION

We, at GREYLINE Instruments, would like to thank you for purchasing our quality American made
ISM 5.0 Insertion Magmeter. As our valued customer, our commitment to you is to provide
reliable service, while continuing to offer you quality products to meet your growing flow
measurement needs.

1.1 PURPOSE OF THIS GUIDE

fast

We have written this guide to provide the persons responsible for the installation, operation and
maintenance of your flow meter with the most specific equipment information they will need.
This is NOT an electrical or plumbing trade manual.

WARNING

Please do not permit persons to install, operate or maintain this equipment unless they have a

This guide is the basic reference tool for all GREYLINE ISM 5.0 Insertion Magmeters. If you have
not purchased all of the options, there will be references in this manual which are not applicable
to your meter(s).

1.2 TYPICAL INSERTION ELECTROMAGNETIC FLOW METER

Faraday’s Law of electromagnetic induction states that a voltage will be induced in a conductor
when it passes through a magnetic field, and the induced voltage will be directly proportional to
the velocity of the conductor.

GREYLINE ISM 5.0 Insertion Magmeters generate pulsating magnetic fields that are used to induce
a voltage into the conductive fluid flowing through the pipe. Electrodes located on the flow meter
sensor head measure the induced voltage. Circuitry within the flow meter electronics
then converts the voltage to digital and analog signals that convey flow rate and total data via
connecting the cable to any of GREYLINE’s display devices, Btu meters and/or to a data
acquisition system.

ADDITIONAL REQUIRED HARDWARE

All GREYLINE insertion type meters can be installed and removed via
a 1” or larger full port ball valve without system shutdown. The terms
“Standard” and “Hot Tap” refer to the installation method of the
isolation valve kit only.

Standard Installation Hardware: For new construction or scheduled
shutdown; once kit is installed, the flow meter can be installed
or removed without system shutdown.

Hot Tap Installation Hardware: For applications which require the
access hole in the pipe to be drilled through the valve using a
wet tap drilling machine while the hydronic system is
pressurized and operating.

NOTE: Installation hardware materials vary greatly based on pipe
material, pipe size and standard vs. hot tap versions.

1.5 ADDITIONAL HARDWARE THAT MAY BE REQUIRED

1.5.1 Grounding Rings

Grounding rings may be required whenever meters are installed in non-metallic or lined pipes.
Grounding rings placed before and after the meter eliminate electrical noise that will interfere
with the proper operation of the meter. GREYLINE provides grounding rings as an optional
accessory. Grounding ring dimensional information and part numbers are listed below. For proper
operation, grounding rings are required before and after the meter.
