When the liquid covers the electrodes it forms a part of an electric circuit causing current to flow.
Radiometric level measurement working principle.
The sensor has a pair of electrodes and applies alternating current to them.
In other study conducted by gao et al the ppyox g hybrid has been used to electrochemically coat the gc electrode and be employed as a working electrode in an electrochemical sensor for the simultaneous determination of adenine and guanine 75 the fabrication procedure of this modified electrode used the three steps electrodeposition method as depicted in fig.
Materials of housin flange are selectable.
A liquid level control system by using a float sensor works on the principle of buoyancy which states a float immersed in a liquid is buoyed towards upward direction by an applied equal force to the weight of the displaced liquid as a result the body drives partially and gets submerged upon the liquid surface and covers the same distance the liquid level moves.
