DESCRIPTION

Technical Description

Four measuring sections with different thermometers can be individually selected using ball valves. The temperatures measured using the resistance thermometer and the thermocouple are displayed digitally. The bimetallic dial and liquid-in-glass thermometers are direct indicating instruments.

The response of the measuring devices for different flows can be investigated. The flow rate is measured with a rotameter. The effect of different installation positions and methods on measurement accuracy can be investigated.
