3.0 INSTALLATION

3.1 Mechanical Installation

Guidelines and Warnings for MT5000 installation:
Do not tamper or remove coupler from transmitter housing as this will damage the coupler.
All Installations
1. Do not mount the MT5000 in the product fill stream.
2. To obtain the best return signal from the product level mount the MT5000 coupler directly into the top of the ves-
sel.
3. Do not mount MT5000 single probes using bushings. (Figure 2)
4. Ideally, probes should be mounted in the center of the vessel to provide the maximum measuring range.
5. Avoid internal obstructions such as tubing, ladders or agitators.
6. An MT5000 installed in a nozzle whose height is greater than its width will have an increased non-linear zone at
the top of the probe.
7. Cable probes with weights should be allowed to hang under the tension of the weight within the vessel. Shorten-
ing of the probe may be required.
8. To avoid excessive movement of the MT5000 probe in an agitated process, or where installation close to the
vessel wall is required, secure the bottom end of the probe to the vessel. Probes installed from top of the vessel
may require the use of a stilling well.
9. Probes installed in side vessel connections require additional probe support within the nozzle connection.
10. Threaded connections should be installed with thread sealant approved for use by the consumer. Flanged con-
nections should be made using materials (bolts, studs, nuts, and gaskets) and procedures (torque specifications)
approved by the consumer.
Assembly Instructions for Loose Shipments:
At times, the rigid probe (i.e. P01 or P02) or flexible cable (i.e. P11 or P12) will be shipped as a loose (separate) as-
sembly. In this case, an identification tag will be attached to the probe/cable to identify the serial number/transmitter
it is associated with.
1. Locate the top end of the probe/cable that has a threaded FNPT connection.
2. Locate the bottom end of the transmitter coupler that has a threaded MNPT connection.
3. Apply LOCTITE 222MS to the MNPT connection.
4. Fasten the probe/cable hand tight to the MNPT connection and allow this to cure for 15 minutes.
5. Ready for installation.
Plastic Tanks, Fiberglass Tanks, and Open Air Installations
1. Single probe units require the use of a metal mounting flange or plate to launch the microwave energy down
length of the probe. A minimum 6 inch (150mm) OD, 3/8 inch (10mm) thick plate should be used.
2. A MT5000 installed in a non-metallic vessel or open air envi-
ronment will be subject to interference from other electromag-
netic devices such as radios. Stilling wells may be required to
eliminate this interference.
Concrete Tanks
1. Tanks constructed of concrete require probe mounting be:
1 ft. / 0.3 m from wall with up to 20 ft. / 6.1 meter measur-
ing length
2 ft. / 0.61 m from wall over 20 ft. / 6.1 meter measuring
length
2. Single probe units require the use of a metal mounting flange
or plate to launch the microwave energy down length of the
