 CONVERTER OVERVIEW
1.0 CONVERTER OVERVIEW
Read this entire manual prior to installation and/or changing any settings. Retain this manual in your records, DO NOT
DISCARD.
The signal converter is the reporting, input and output control device for the sensor. The converter allows the measurements,
functional programming, control of the sensor and data recording to be communicated through the display and inputs
& outputs. The microprocessor-based signal converter has a multi-point curve-fitting algorithm to improve accuracy, an
8-line graphical LCD display with three-button touch programming, and a rugged enclosure that meets IP67. In addition
to a menu-driven self-diagnostic test mode, the microprocessor continually monitors the converter's functionality. The
converter will output rate of flow and total volume. The converter also comes standard with password protection and many
more features.

2.0 INSTALLING THE CONVERTER AND CABLES

2.1 Verify Serial Numbers
The converter and sensor are supplied as a matched system. Verify the meter serial numbers on both the converter and
sensor match. This will ensure a properly calibrated system.
The tag on the side of the converter has the converter model number, the converter serial number, the meter model
number and the meter serial number. An example is shown below (Figure 1).

i
IMPORTANT: Verify the Meter Serial Numbers on both the converter and sensor match. This will ensure a
properly calibrated system. The Meter Serial Number is located on the side of the sensor, and the Converter
Serial Number and the Meter Serial Number are located on a label on the side of the converter. Ensure the
Meter Serial Number on the sensor and the converter tags match.

2.2 Mounting The Converter

If possible mount the converter in an electronics shed or environmental enclosure. If the converter is mounted outdoors a
sun shield is recommended. The sun shield should be oriented in a direction to reduce sun damage and ensure readability.
The converter is mounted using 2 bolts. (See Figure 21) A service loop in the cables is required. (See Section 2.3) This
electronic unit is rated IP67 for temporary flooding.

Page 2 30122-46 Rev. 1.3 | 27OCT2020

 INSTALLING THE CONVERTER AND CABLES
2.3 Installing Cables To Converter And Service Loop
Conduit of any kind CANNOT be attached directly to the electronics enclosure. Attaching conduit directly to the enclosure
will introduce dangerous gasses and moisture into the enclosure creating a dangerous condition, and will remove the
enclosure's IP67 rating. Attaching conduit to the enclosure or altering the enclosure in any way will void the warranty.
Any cable running through a conduit must exit the conduit and have a minimum of an 8" service loop before entering
the electronics enclosure through the cable glands. All cable compression glands must be properly tightened to prevent
moisture intrusion and maintain the IP67 rating. This allows the electronics enclosure to be rotated and the rear panel to
be accessed. If electrically bonding (grounding) the enclosure to metallic conduit or raceways, secure a lead wire to the
enclosures back panel screw and attach the lead to a listed and approved conduit grounding bushing. (See Figure 2) To
insure IP67 rating use only round cable 0.125" to 0.375" in diameter.

WARNING: Do not connect any form of conduit directly to the converter enclosure. Doing so will allow moisture
! and potentially dangerous gasses to enter directly into the converter. Attaching any conduit to the enclosure, or
altering the enclosure in any way will void the warranty.

 INSTALLING THE CONVERTER AND CABLES
2.4 Pulling Sensor Cable Through Electrical Conduit
It is very important to protect the end of the sensor cable when pulling it through a conduit. Water can accumulate in low
portions of conduit. Always use the factory supplied cable cover, or similar method, to seal the end of the cable against
water when pulling the cable through conduit. See Figure 3. This will ensure proper operation of the meter.
1. Tie a rope or cable-snake securely around the middle of the cable cover.
2. Carefully pull the rope or snake until the sensor cable end clears the conduit.
3. Bring the cable end to the converter location. If necessary, secure the cable so that it does not fall back through the
conduit.
4. Remove the cable cover by pulling the rip wire. The cable cover will tear off (discard the cover).

i
CAUTION: Do not cut the cable cover off. Doing so may damage the sensor cable and adversely effect the
calibration of the meter.

Each sampling frequency mode has a different effect on battery life. Note that the battery life shown below is under optimal
conditions:
An internal algorithm allows the unit to automatically detect flow rate variations in the process.
• Continuous sampling: < 6 months
This capability determines the automatic setting of the sampling frequency. No variations means
lower sampling frequency, with less power consumption; high variations means higher frequency
• Average sampling: > 5 years
to better follows the changes in the process.
• Max life sampling: > 7 years
• Smart sampling: 1-5 years depending on flow profile

Note: Continuous sampling is only available if energy saving is turned off. Energy saving can only be accessed through the
IF2 communication cable.
