IMP+ can be simply mounted on a bracket, suitable for the application 
and secured using the thread located at the top of the transducer 
(2"BSP/NPT). 
Care should be taken to ensure that the IMP+
IMP+IMP+
IMP+ is not installed in direct 
sunlight, in order to avoid errors in the measurement of ambient 
temperature.   
Attention should also be taken, when mounting the unit, to ensure that 
strong windy conditions are avoided, wherever possible, to prevent

IMP+ can be simply screwed into a flange and 
secured using the thread located at the top of the transducer (1.5" or 2"BSP/ 
NPT, dependent on model). 
Where possible use a flange made of a synthetic material such as PVC, in 
cases where a metal flange is used it is advisable to fit a suitable gasket 
between the flange of the IMP+
