Purpose of this Document

PURPOSE OF THIS DOCUMENT

The purpose of this document is to provide instructions the installation, wiring and operation of the VN2000 Transmitter.

MPORTANTI

Read this manual carefully before attempting any installation or operation.
Keep the manual in an accessible location for future reference.

UNPACKING AND INSPECTION

Upon opening the shipping container, visually inspect the product and applicable accessories for any physical damage such
as scratches, loose or broken parts, or any other sign of damage that may have occurred during shipment.

OTE:N If damage is found, request an inspection by the carrier’s agent within 48 hours of delivery and file a claim with the

carrier. A claim for equipment damage in transit is the sole responsibility of the purchaser.

Storage

If the meter is not scheduled for installation soon after delivery and must be stored:

• After inspection, re-pack the meter into its original packing.

• If the meter being stored has been previously installed, remove all process fluids and corrosives.

• Store in a clean, dry site free of mechanical vibration, shock and chemical corrosives.

INTRODUCTION

The VN2000 Transmitter is supplied with all vortex flow meters. It is designed to be located on the head of the meter or
remotely mounted from the meter, for easy viewing and access. Three configurations are available:

• The VN2000 Volumetric Flow Transmitter has a large, easy-to-read LCD indicator that displays flow rate and accumulated
total flow.

• The VN2000 Mass Flow Transmitter also displays temperature compensated flow rate.

• The VN2000 Energy Flow Transmitter also displays compensated flow rate (BTU/hr or kBTU/hr), total flow (total BTU),
operating temperature, and outgoing and returning temperature.

The control panel keys used to program parameters including engineering units, line sizes (insertion only), 4…20 mA span
adjustments and to recalibrate for new flow conditions.

All internal parameters of the flow meter can be read via the VN2000 Transmitter.

The transmitter has a built-in non-volatile memory for setup and calibration data with the ability to field-calibrate. All
transmitters are factory-tested and programmed.

Installing the Transmitter

INSTALLING THE TRANSMITTER

The remote transmitter enclosure has a mounting bracket for wall mounting. Locate the enclosure within 30 feet of the
pipeline sensor and at eye level for easy viewing and access to the control panel keys for programming.

Wiring

WIRING

The transmitter ships with a cable that has a connector on one end and flying leads with 4 or 5 wires on the other end. Use
this cable to wire the power and outputs. The transmitter is available with two output options:

• 4…20 mA/pulse output; uses a 4-wire cable

• Modbus RTU; uses a 5-wire output

Table 1: Wiring

Grounding

Ground the power supply to DC ground or good earth ground. DO NOT connect to AC ground.

Analog Version, 4…20 mA

To wire for power, use 24 gauge with multi-pin power connector supplied with meter. Do not run the wire over transformers,
motors, or any other magnetic field generating devices. Connect the end of wire to 24V DC for loop powering the device.

Connecting Cables

CONNECTING CABLES

Connecting to the flow meter is easy using our plug-and-play design. No internal wiring is required. All cables are included
with the meter.

Table 2: Transmitter cables

1. Connect the wired end of the cordset to the power supply and outputs.

OTE:N DO NOT USE 110…220V AC without using an optional AC-to-DC power supply, available as an accessory.

2. Connect the other end of the cordset into the remote transmitter. Find the matching keyway between the plug and the
connector in the enclosure. When the key nds the grooved slot, push the plug into the connector.

3. Slowly tighten the threaded connection. Make sure the plug is tightened all the way down into the plug socket.

4. If the transmitter is mounted remotely, use the cordset with connectors on both ends to connect to the sensor.

5. If the meter is an energy meter with an external RTD, use the cordset with connectors on both ends to connect to the
external RTD. The external RTD and remote sensor cable are identical.

6. Apply power to the power supply.

7. The screen displays the version of the operating software.

8. After approximately 5 seconds, the rate and total display (if ow is present).
