4. Installation
4.1. Equipment List
The CODEL Model V-CEM5100 comprises the following:
-
2 x transducers with 10m of cable (standard length)
-
2 x site mounting flanges
-
2 x insertion tubes
-
2 x air purges
-
1 x Power Supply Unit (PSU)
-
1 x Signal Processor Unit (SPU)
-
1 x Data Display Unit (DDU)
4.2. Siting the Equipment
The equipment is designed for mounting on boiler ducting or stacks in positions open to the weather. It is fully
sealed to IP65 and requires no weather covers.
Consider the following:
-
the transducer
s must be located such that there are no ‘upstream’ bends, changes in duct diameter
or obstructions within the duct, for a distance of 3-5 duct diameters. In addition, we recommend that
the transducers should be a minimum of 4 duct di
ameters ‘downstream’ of the fan. If unsure, please
contact CODEL for technical advice.
-
the site must be accessible for servicing both transducers
and
-
transducers should be mounted in the same plane as the flow and we recommend a 1m separation
for most applications. If unsure, please contact CODEL for technical advice.
-
the SPU should be mounted local to the transducers and is supplied with 10m of cable as standard.
The transducers need to be mounted so that a maximum pathlength is achieved whilst maintaining an
acceptable confidence level. Ideally, a separation of 1m should be used. However, this will depend on plant-
specific flow patterns. Maximum accuracy of measurement corresponds to maximum time of flight but, if high
turbulence exists the ‘fingerprint’ of the flow may be short, thus the pathlength (transducer separation) should be
reduced; whatever the arrangement ensure that an acceptable level of correlation coefficient is recorded.
4.3. Installation
The analysers and any other items are normally protected for transportation by an expanded foam packing
material. When unpacking, please ensure that smaller items are not discarded with the packing material.
The analysers are supplied with standard 10m cables already connected.
If any items are missing please inform CODEL or your local CODEL supplier immediately.
The installation site should be free of all encumbrances and safety procedures should be observed at all times.
The recommended order, reflected in this manual, is:
Installation of the stub-pipe and mounting flange
Installation of insertion tubes, air purges and purge air supply
Fitting of transducer heads, PSU, SPU and DDU
Installation and connection of cables
