Introduction
General
This manual contains information concerning the appli-
cation, installation, and operation of the HMS3700 and
HMS3770 insertion flow meters. Keep a copy of this
manual with the flow meter for future reference.
Applications
LCMag electromagnetic flow meters are designed for liq-
uid flow measurement in most industries including water
& waste water, food & beverage, pharmaceutical, chemi-
cal, and more. These meters are not suitable for mea-
surement of petroleum products, and other liquid media
with low electrical conductivity. Minimum electrical con-
ductivity of measured liquids is 5µS.
Basic Components
An LCMag electromagnetic flow meter system consists
of two basic components: the flow meter, and the con-
verter. The flow meter is the tube which inserts through
the wall of the pipe and into the liquid flow for measure-
ment. The converter is the electronic control that pro-
vides power to the flowmeter and provides signal pro-
cessing, flow calculation, and display outputs for the user.
The wetted parts of the flow meter (liner and electrodes)
must be selected for compatibility with the liquid being
measured.
The converter must be selected for compatibility with the
environment in which it will operate.
Unpacking
Always inspect the instrument for damage from shipping
upon receipt. File a damage claim with the carrier if dam-
age is discovered.
Transportation and Handling
Do not lift the instrument from the carton by the con-
verter head. Use lifting eyes where provided for larger
meters, or lift by the sensor body.
When transporting, never use forks of a forklift, chains,
wire slings, or any other object in the flow tube of the
meter. Serious damage to the instrument will result.
Start up and Maintenance
• Before starting up the instrument, always make sure
that there is a suitable connection to ground as de-
scribed on Page 5 of this manual.
• Periodically verify the following: the integrity of the
power supply cables, the proper tightening of the
sealing elements (cable glands, covers, etc.), the me-
chanical attachment of the instrument to the pipe or
to the wall stand.
Safety Legend
Before using the instrument, always establish a reliable electrical connection to ground.
Avoid any attempt to repair the instrument. If the instrument is not functioning properly, please call
the nearest authorized representative.
Pay maximum attention during operation.
