Hi,
Is it possible to scale the 4 to 20mA output of a Vegaflex 63 TDR Level Senor mounted on an inclined horizontal cylindrical diesel tank with domed torispherical ends, for volume in litres, by using the dipstick strapping table as a look up table in the M340 using Unity Pro?
I have tried numerous partially filled horizontal cylindrical tank with domed torispherical ends volume formulas but none seem to come close to the dipstick values. The closest I can get is with a 6th order polynomial formula derived from Excel LINEST function but do not know how to apply this to the 4 to 20mA value.
I also not sure of the best configuration of the Vegaflex 63 4 to 20mA output e.g. to use linearization and how to interface this to the PLC.
Regards El
