Installation and mounting

If the installation is going to occur in a hazardous area, completely read the Agency Information section before starting any work. The Agency
Information outlines additional regulations that need to be followed in order for the installation to comply with hazardous area regulations.
This section contains information about storing your transmitter (prior to installation) and detailed procedures for installing and mounting your
transmitter.

Storage

If storage is required prior to installation, store indoors in a dry environment at ambient temperature range not exceeding -40 °C (-40 °F) to
71 °C (160 °F).

Stilling wells and guide poles

Level Plus transmitters can be mounted in slotted or unslotted stilling wells but a slotted stilling well is always preferred. Using a unslotted
stilling well will negatively affect performance of any level device as the level in the stilling well can differ from the level in the tank. The Level
Plus transmitter can also be installed to one side of the stilling well to also allow for sampling and manual gauging from the same opening as
the automatic tank gauging. Contact Technical Support for details.
Level Plus transmitters do not require a stilling well for installation. Our transmitters are installed in numerous tanks without stilling wells with
no loss in performance due to our patented flexible waveguide and hose. A stilling well is highly recommended for agitated, turbulent, and/or
fast filling tanks.

Installation

The installation procedures below are illustrated using the adjustable NPT fitting for a threaded flange mount. The procedures will have to be
slightly adjusted if using a welded flange or sanitary Tri-Clamp mount.

RIGID PROBE

Tools Required:
• Channel lock pliers
• Common screwdriver
• 5/32 in. Hex key (allen wrench)
Caution:
It is recommended that assembly and mounting of this transmitter should not be performed alone. To ensure proper and safe assembly of the Level
Plus transmitter, a minimum of two (2) individuals are recommended. Gloves are also recommended. In addition , PPE is required for work areas such
as safety shoes, safety glasses, hard hat, and fire resistant clothing.
Perform the following steps to Install the RefineME transmitter:
1. Remove the stop collar and E-ring. With assistance, feed the rigid pipe through the hole of the removed tank flange until the flange is
positioned near the top of the transmitter. Insert the threaded portion of the adjustable fitting into the customer supplied flange and
tighten (apply pipe thread sealant if required). Be careful not to drop the flange as it can damage the transmitter.
2. Slide the product float onto the rigid pipe. Slide the interface float (optional) onto the rigid pipe. Install stop collar 2 inches from the
bottom (see 'Note' below). Do not drop the float(s) or allow them to free fall along the rigid pipe as damage may result.
Note:
The stop collar can be removed or adjusted based on the float selected for the application. Please consult the factory for more information.
3. Slide float(s) back down to the stop collar to prevent them from free falling during installation into the tank. Insert the rigid pipe
(with floats) through the tank opening and lower the transmitter/float assembly into the tank until it rests on the bottom. DO NOT
DROP OR DAMAGE THE PIPE.
4. Secure the flange onto the tank mount.
5. Pull the transmitter upward so the end plug is just resting on the floor of the tank. Tighten the adjustable fitting to hold the transmitter
in place.
6. Terminate the field wire cables noting proper wire orientation.
