Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This device must be installed to ensure a minimum antenna separation distance of 8 in. (20 cm) from all persons.
The power module may be replaced in a hazardous area. The power module has surface resistivity greater than
one gigaohm and must be properly installed in the wireless device enclosure. Care must be taken during
transportation to and from the point of installation to prevent electrostatic charge build-up.
Shipping considerations for wireless products
The unit was shipped to you without the power module installed. Please remove the power module prior to
shipping the unit.
Each power module contains two “C” size primary lithium batteries. Primary lithium batteries are regulated in
transportation by the U.S. Department of Transportation, and are also covered by IATA (International Air
Transport Association), ICAO (International Civil Aviation Organization), and ARD (European Ground
Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure compliance with these or
any other local requirements. Please consult current regulations and requirements before shipping.

1.0 Rosemount 2160 Overview
The Rosemount 2160 Wireless Vibrating Fork Level Switch (“level switch”) uses
vibrating short fork technology, and is suitable for virtually all liquid applications.
The level switch is designed to use the principle of a tuning fork. A piezo-electric
crystal oscillates the forks at their natural frequency (~1400 Hz). Changes to this
frequency are continuously monitored. The frequency of the vibrating fork sensor
changes depending on the medium in which it is immersed. The denser the liquid,
the lower the frequency.
When used as a low level alarm, the liquid in the tank or pipe drains down past the
fork, causing a change of natural frequency that is detected by the electronics and
switches the output state to a dry condition. When the level switch is used as a high
level alarm, the liquid rises in the tank or pipe, making contact with the fork which
then causes the output state to switch to a wet condition.
The switch output state, along with other parameters, are regularly transmitted over
a secure wireless connection to a Smart Wireless Gateway (“gateway”).

2.0 Before Installation
2.1 General considerations
The level switch is available as an intrinsically safe version for hazardous area
installations. There are ordinary location versions for unclassified, safe areas.
The weight of the level switch with a heavy flange and extended fork length may
exceed 37 lb. (18 kg). A risk assessment is required to be done before carrying,
lifting, and installing the level switch.
Handle the Rosemount 2160 with great care (Figure 2).
This level switch is designed for open or closed tank and pipe installation.
It is weatherproof and protected against the ingress of dust, but must be
protected from flooding (Figure 3).

Quick Start Guide
Mount the switch so that the battery side is accessible.
Clearance of 2
On the circuit side of the electronics housing, provide 0.75 in. (19 mm) of
clearance for units without an LCD display. Three inches of clearance is required
for cover removal if an LCD display is installed.
The housing can be rotated for optimal viewing of the optional LCD display and to
get the best antenna position (see “Housing rotation (optional)” on page 5).
Always ensure a proper seal by installing the electronics housing cover(s) so that
metal contacts metal. Use Rosemount O-rings.
Always ground the housing in accordance with national and local electrical codes.
The most effective grounding method for the housing is a direct connection to
earth ground with minimal impedance.

/8 in. (60 mm) is required for cover removal.
2.2 Installation recommendations
Avoid installing near liquid entering the tank at the fill point.
Avoid heavy splashing on the forks.
Avoid installing near heat sources.
Ensure the fork does not come into contact with a tank/pipe wall or fittings.
Allow a distance between product build-up and level switch fork (Figure 4).
Figure 4. Avoid Product Build-up
2.3 Housing rotation (optional)
1. Loosen the housing rotation set screw (Figure 5 on page 6).
2. First rotate the housing clockwise to the desired location. If the desired location
cannot be achieved due to the thread limit (up to 360°), rotate the housing
counter-clockwise to the desired location. Do not over twist.
3. Re-tighten the housing rotation set screw.

3.0 Wireless Preparation
3.1 Power-up sequence
The power module should not be installed on any wireless device until the Smart
Wireless Gateway (“gateway”) is installed and functioning properly. This level switch
uses the black power module. Order model number 701PBKKF.
Wireless devices should also be powered up in order of proximity from the gateway,
beginning with the closest. This will result in a simpler and faster network
installation. Enable Active Advertising on the gateway to ensure new devices join the
network faster.
For more information, see the Smart Wireless Gateway Manual

.
3.2 Antenna position
The antenna should be positioned vertically, either straight up or straight down, and
should be approximately 3 ft. (1 m) from any large structure or building to allow for
clear communication to other devices.
4.0 Physical Installation
1. Install the level switch according to standard installation practices, making sure
to correctly align the fork using the alignment notch or groove (Figure 4).
2. Use supports for extended fork lengths greater than 3.2 ft. (1 m).
Refer to the Rosemount 2160 Reference Manual
3. Close the housing cover and tighten to safety specification. Always ensure a
proper seal so that metal touches metal, but do not over tighten.
4. Insulate the level switch with ROCKWOOL
Reference Manual
5. Position the antenna such that it is vertical, either straight up or down.
6. Plug in the power module after the gateway is installed and functioning
(Figure 7 on page 8).
