hi all,
we have a water tank with level transmitter DELTAPILOT_S - DB50L {ENDRESS + HAUSER} containing FEB 22 insert and FHB 20 display. it is connected to PLC and SCADA. we recently replaced the transmitter with a new one and also changed the address on PLC as its slot got damaged.
the problem is that we calibrate it as per operation manual and it gives correct reading when empty and when full giving 4 & 20mA respectively. but when empty its gives an error in SCADA indicating the current is below 4mA or -9% level, while the transmitter is giving 4mA signal. when the tank reaches certain level the error goes away.
when the tank is full the trasnmitter reads correctly and gives 20mA, but in the SCADA it reaches 50%level.
what could be the reason for this? kindly assist. thanks
