1. General Introduction
Rosemount 765 Multi-input Temperature sensor is integrated with water level sensor which also measure free water level at the bottom of the tank which enable correct measurement of volume. It is hung vertically from the top of the tank, and the position/length is chosen according to the actual bottom water range. 765 Multi-input Temperature sensor should be anchored to the tank bottom to ensure a fixed position in case of turbulence. One of the Pt-100 temperature sensor elements can be installed inside the water level probe allowing temperature measurements at low levels. The water level sensor delivers a digital signal, and is connected to the Rosemount 2240S Multi-input Temperature Transmitter.
