1.3 Site Considerations
Because the relative location of the flowcell and the electronics enclosure is important, use the guidelines in this
section to plan the XMT868i installation.
Figure 1 below shows a typical installation.
Figure 1: A Typical Model XMT868i System
1.3.1 Electronics Enclosure Location
The standard Model XMT868i electronics enclosure is a powder-coated, cast-aluminum, Type-7/4X explosion-proof
enclosure, and an optional stainless-steel enclosure is available. Typically, the enclosure is mounted as close as possible
to the transducers. When choosing a site, make sure the location permits easy access to the electronics enclosure for
programming, maintenance and service.
Note:
For compliance with the European Union’s Low Voltage Directive, this unit requires an external power
disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such, clearly
visible, directly accessible, and located within 1.8 m (6 ft) of the unit.
1.3.2 Flowcell Location
Ideally, choose a section of pipe with unlimited access; for example, a long stretch of pipe that is above ground.
However, if the flowcell is to be mounted on an underground pipe, dig a pit around the pipe to facilitate installation of
the transducers.
