Tank and reservoir levels can be externally measured using the testo 875 or the testo 881
Readily check fluid levels in sealed tanks with a brief scan using one of testo’s thermal imagers. Since the liquid and gas portions in a tank heat and cool at differing rates, the liquid levels can be verified (e.g. after the sun warms a tank, or night time cools). This easy check gives tank operators an assurance that automated systems are registering properly, and the consequences of mistaken indicators are avoided.
High temperature measurement extension
The testo 881 can be fitted with a special lens-cover, extending the high-temperature limits that the testo 881 can measure. This means that the instrument can accurately provide measurements up to 1022ºF (550ºC) for many applications in a hot plant environment. This option is a must for all high temperature process plants and large engine applications.
