Question

What type of sensor would you choose to measure the level height of Hydrochloric acid inside of a reservoir?. This sensor provides the feedback, so the controller gradually reduces the flow rate to not overflow the tank.

Indicate the position of the sensor with respect to the tank

a) tank is transparent

b) tank is not transparent

c) Should we have a safety sensor?

d) Safety vale?

Answer 1

continuous leve lsensors are used to measure the the height of the HCL inside a reservoir. these sensors provides feedback and gradually reduces the floew rate and not overflow the tank.

the position of the sensor is placed near to the level of the tank. and here we are using continuous level sensors and it gives accurate value.

and the tank is need not be transparent and there is no ned of using safety valve and no need to use safety sensor.

so the position of the sensor with respect to tank is not transparent.
