The number of sections in the draft gauge system

No	Parts	Qty.
1	Pressure Transmitter/ Transducer	4 unit	Fwd Left, Fwd Right, Port, Starboard
2	Gate Valve Control	4 unit	Fwd Left, Fwd Right, Port, Starboard
3	Differential Pressure Pipe Installation	4 set	Fwd Left, Fwd Right, Port, Starboard
4	MDU (Master Display Unit)	1 unit	Bridge
5	Substation with I/O Module ( barrier)	1 set	Bridge (for 4 unit input signal from Transducer

Pressure Transmitter Unit

Sections that must be checked

a. Pressure Transmitter 

• Pressure Transmitter calibration should be done, to ensure that the device is working properly. 

b. Gate Valve

• Checking function of gate valve to avoid clogging the drain hole. Because disfluencies can reduce the flow of water pressure. 

Pressure Transmitter Unit and Pipe Installation

c. Differential Pressure Pipe Installation

• Checking function of differential pressure pipe installation to avoid clogging the drain hole. Because disfluencies can reduce the flow of water pressure. 

d. MDU

Differential pressure Transmitter Pipe Installation

• Adjustment values ​​/ parameters are the same as the results of the calibration has been done. 
• Substation with I/O Module To ensure that the module is still processing the input from the transducer and feeding into the MDU.
•
