Very useful, thank you. One question, can i not use pressure regulator in the first place and use the actual water level to calibrate? If yes, what difference would that make? Anyone please ...
An Amazon $80 Riiai 4-20mA 0-24V precision 0.01mA calibrator will work just fine. Hundredth's of a milliamp is adequate. This will save $13,000 of buying a Fluke 754 😎 Nice video
at minutes 3 you start sir to connect high side to regulator and Instrument Air Supply !!! this made me confused ... what I know , its connect to process - bottom of a tank
ok .... why you not use pressure transmitter for open tank instead of using DP Transmitter. as you know, its more expensive ... plus a manifold related to differnial transmitter is more expense than manifold of pressure transmitter...in addition, you dont have to wary about low side to elemenate dust and wind impact.
U don't need a 250 ohms resistance if u are not hooking communicating device...... The 1151 series transmitter are purely analog and are not hart enabled, the there will be no beed to reduce the loop impedance. Thanks 🙏
cause its the equivalent pressure of the reference or datum line of the tank. it is the measured pressure where tank is considered zero level. it is common in level measurement to compensate the sludge or sediments settling down at the bottom of the tank.
