I am looking for 60 meter water level transmitter for a Surge Tank having diameter of 10 meters of a Hydro Power Plant. The water level can have sudden rise of level (in few seconds) and with water force upwards when the plant is stopped suddenly.
I thought of two options:
1. Ultrasonic based
2. Submersible pressure transmitter
Ultrasonic will be costly option being large range. And may give slow and false readings due to direct and reflected waves from tank walls. Please suggest options, who support such high range, as mostly 25 meter range is the limit for Ultrasonic, and if it will be correct choice?
Submersible Pressure Transmitter seems to be OK, in terms of response, range and cost. But what may happen when sudden surge comes and water rises with great force upwards, will the sensor remain at its location or may flow down in the overflow exit near top level.
Thanks
