The level transmitter in Figure 1 has a range of 0 to 8 ft and a time constant of 3s. If the measured water level in the boiler drum is 3 ft, determine the current signal, the percent transmitter output to the controller and the gain of the transmitter. Write the transfer function and draw the block diagram of the level transmitter.
