First WRAS ‘certified’ submersible
level sensor
VEGA Controls is proud to announce
another innovative first for the water
sector. They have achieved the first ever
WRAS approval of a submersible pressure
sensor as a whole device.
This means a full product certificate
number registration and listing on
the WRAS approved product list. The
VEGAWELL submersible pressure sensor
is the first and only transmitter of this
type to be fully WRAS certified and
meets the requirements of Regulation 31
(4)(b).
The WRAS certification means it will not
contaminate or harbour microbial growth
when used in potable or drinking water.
This enables it to be deployed anywhere
on the water supply chain: from the With ranges from 0.1 Bar to 60 Bar, heart of a water treatment facility, are enforced by the UK water supply

Ray Tregale, Managing Director of VEGA
Controls said, “This is an important
first for us and our customers who
want to use submersible pressure
sensors in drinking water supply. We
want to distinguish the difference of
this certification - we put in a lot of
time and effort to achieve it - as many
manufacturers designate sensors as
‘approved’, but in reality they are not
WRAS certified or listed on the WRAS
website.” He added, “The certification
of the VEGAWELL 52 also gives water
supply companies peace of mind as it also
conforms to Regulation 31 (4)(b)” from
