6. Installation and mounting

6.1 Training

Installation should only be conducted by qualified service person-

nel according to local regulations or Temposonics trained service

technicians. Temposonics offers web based and in person training for

installation, commissioning, maintenance, and repair. Temposonics

also offers factory direct services for these same functions. Contact

Temposonics to discuss training or factory direct services before

starting.

6.2 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.

6.3 Tools

• Adjustable pliers

• Large pipe wrench

• Common head screwdriver, slotted screwdriver

6.4 Installation steps

Caution:

It is recommended that assembly and mounting of this transmitter

should not be done alone. To ensure proper and safe assembly

of the level transmitter, a minimum of two (2) individuals are

recommended. Gloves are also recommended. PPE may be required

for work areas such as safety shoes, safety glasses, hard hat, and

fire resistant clothing.

1. Consult chapter 4.3 before starting.

2. Perform steps 1-10 in chapter 8.4.1

3. Remove stop collars from rigid pipe.

4. Slide NPT adapter or flange onto rigid pipe and secure the

adapter/flange. To prevent damage to rigid pipe keep the adapter/

flange supported and towards the end of the level transmitter.

5. Slide the product float onto the rigid pipe. Slide the interface float

(optional) onto the rigid pipe. Install stop collar so the magnet of

the float is 64 mm (2.5 in.) from the tip of the rigid. Do not drop

float(s) or allow them to free fall along the rigid pipe as damage

may result.

NOTICE

The bottom stop collar can be removed or adjusted based on the

float selected for the application. Please consult the factory for more

information.

6. Slide float(s) and adapter or flange assembly back down to the

stop collar to prevent them from free falling during installation

into the tank. If you are using the o-ring stop collar it will not

support the weight of the adapter or flange. Insert the rigid pipe

and floats through the tank opening and lower the transmitter

float assembly into the tank until it rests on the bottom.

7. Connect the adpter or flange to the mating connector on the tank.

8. Connect the 3/4" NPT (rigid) to the adapter or flange

assembly. Tighten the NPT fitting to the adapter or flange. It is

recommended to use anti-seize on the connection.

9. Connect cable to connector.

10. Terminate the pigtail cable noting proper wire orientation. Wiring

diagram is shown in Section 7.

Consult Section 5.7 Technical Drawing to reference what the finished

installation should look like.
