SIR MAY I KNOW IF RADAR TYPE LEVEL TRANSMITTER SHOWING IN THE FIELD 0 % LEVEL AND IN DCS SHOWING 100% THEN WHAT IS THE CAUSE I CLEAN THE CHAMBER & TAKEN ONLINE BUT ONLY ONCE ITS BECOME ZERO IN DCS BUT AGAIN 100% SHOWING IN DCS,THEN I REMOVE THE POWER SUPLLY AND CONNECT IT AGAIN .IS IT OK BUT STILL IN THE DCS ITS 100% AND ON THE DISPLAY ITS INITILAZIATION PLEASE HELP ME READRING THIS?

2209if we open the inlet of an air regulator ,how it will affect the out put of regulator? (out put of regulator is using to operate an on-off valve.it is an air to open valve,and valve is in open position.my doubt is air regulator will hold the valve in open or not,if there is no consumption or leak in regulator out put side ,we only loose the input pressure.)

We are using Rosemount 5400 series Radar Level Transmitters in all types of Sump Applications having oily water hdrocarbon petrochemical nature. What we are facing the problem frequently is that always getting reading frezzed at some value. If we do power recycling , sometimes it is working . then making same freezing problem. If anybody faced before such type of problem and also having solution , Please give the answer.

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.
