Introduction
Liquid Controls offers a broad selection of electromagnetic
(Mag) flow meters for industrial, water, and waste water
flow measurement applications, worldwide. The LCMag
family consists of seven sensor models for specific
applications. The models include micro-flow, wafer,
sanitary, flanged, pipe clamp, and insertion meters. The
units are offered in a wide variety of sizes, materials, and
flow ranges for many industrial and OEM applications.
The LCMag family of electromagnetic flow meters offers
the best solution for measuring the flow of electrically
conductive liquids (5µS/cm minimum), for the following
reasons:
• Accuracy is not affected by fluid characteristics such
as viscosity, density, temperature, or suspended
solids.
• No moving parts.
• Virtually no pressure drop.
• Clean-in-place construction (HMS501 and HMS2410
with remote converter only).
• Minimal maintenance.
• Easy to install and operate.
• Wide range of nominal diameters from 1/8" to 72".
• Wide range of flow rates from as low as 0.1 GPM to
as high as 400,000 GPM.
• Automatic, dual flow range capability.
• Broad selection of liners, electrode materials, and
process connections.
• High, full-scale accuracy, ±0.2% over a 10:1 range
(for liquid velocity greater than 4 ft/second) with some
sensor/converter combinations.
LCMag meters are available in a full selection of
configurations and sizes. Models are available in flow
ranges from 0.10 GPM to 400,000 GPM and in process
fittings from 1/8" NPT to 72" flanged meters and up to 80"
for insertion meters. Connections include flanged,
threaded, wafer, pipe clamp, and sanitary. A scaled, digital
pulse output is standard. A wide range of additional outputs
are available. These include: analog (0–20mA or 4–20mA)
serial (RS-232 or RS-485), relays, Profibus DP, additional
inputs, and data logger.
HML210 mounted on an HMS2500 Flange Sensor
The HML210 Converter is for use with all HMS series
flow sensors (except HMS600 and HMS5000). The
converter is a programmable, microprocessor-driven unit
providing automatic zeroing, EEPROM data protection on
loss of power, empty pipe detection, and self diagnostics.
The optional display matrix is 128 x 64, 8-line (16
characters per line) with three external membrane
programming keys.
Features
• Available with three external membrane programming
keys
• IP67 rating
• Available with an LCD display; 8 lines, 16 characters,
backlit
• Two digital outputs
• Four internal totalizers
• Panel mount configuration available
Accuracy
Capable of ±0.2% for liquid velocity > 4 ft/sec (with full
bore sensors)
Repeatability
Capable of 0.01% or better

Safety
Before applying power to the instrument please,
verify the following:
• Power supply voltage must correspond to that
specified on the name plate of the instrument.
• Electrical connections must be made as described
on pages 8-9.
• Ground connections must be correctly installed.
Periodically Verify:
• The integrity of the power supply cables, wiring, and
other connected electrical equipment.
• The integrity of the instrument’s housing. The
housing must not have any damage that could
compromise the environmental sealing.
• The torque setting of elements such as cable glands,
covers, etc. (Use supplied fittings if using hard
conduit).
• The integrity of the front panel, display, and keyboard.
Damage may compromise the environmental sealing.
• The mechanical attachment of the sensor to the pipe
and the converter mounted to a wall (for remote
converter mounting).
Grounding Instruction
For correct operation of the instrument, it is essential
that the sensor and the liquid are at the same electrical
potential. Always connect the sensor and converter to
a dedicated earth ground.
Always establish a reliable electrical connection to ground before using the instrument.
Verify that the supply voltage is the same as written on the nameplate of the converter.
Ensure that the power supply voltage is not connected to the outputs or to any terminals of terminal
blocks M1 or M2.
Carefully close the rear cover of the converter when the electrical connections are completed.
Do not open the converter’s rear cover when the power is on.
Avoid any attempt to repair the converter or sensor. If the system is not functioning properly, please
call the nearest authorized service center.

Wiring Instructions
Sensor to Converter Connection
There are several options for the Sensor to Converter
interface.
• HML210 Converter mounted integrally on the sensor
(compact).
• HML210 Converter mounted remotely from the
sensor (remote). This requires cable assemblies
C015 and C016.
• HML210 Converter mounted remotely from the
sensor in a panel (remote).
If the HML210 is mounted remotely from the sensor, the
following guidelines must be adhered to:
• Maximum distance from the HML210 to the sensor
is 30 ft for fluids with a conductivity less than 200µS
(micro siemens).
• Maximum distance from the HML210 to the sensor
is 65 ft for fluids with a conductivity greater than
200µS.
For applications where these conditions are not met, a
preamplifier is required. This mounts directly on top of
the sensor. With a preamplifier installed, the maximum
distance from the sensor to the HML210 is 1,640 ft
(500m).
NOTE: For proper installation, the cables must be ordered
with the unit. User supplied cables may void warranty
coverage and could affect the functioning of the meter.

NOTE: Maximum length of cable C014 is 1,640 ft (500m).

Wiring Instructions
Connecting Power to the Converter
As described in the Technical Specifications on page 5,
there are three different configurations for converter input
voltage. Before connecting the power source to the
converter, verify that the supply voltage falls within the
limits indicated on the converter nameplate.
•The power supply line must be equipped with an
external device for overload protection (10A
maximum fuse or circuit breaker).
•Ensure that a circuit breaker is installed in proximity
to the converter and is clearly identified and easily
accessible by the operator.
•Use only approved (fireproof) conductors for all field
wiring.
NOTE: The converter for DC power supply (10-35VDC)
is not protected against reverse polarity. Do not apply
reverse polarity voltage.
