DP Level transmitter configuration can be very time consuming. Yokogawa DPharp EJA/EJX Pressure transmitters realize reduction in man hours by smart level setup feature.
Yokogawa DPharp EJA/EJX Pressure transmitters do not need frequent re-zeroing due to superior long term stability, it contributes to reduce maintenance time.
Differential pressure level measurement has an enemy- temperature. Temperature can have a negative effect on the accuracy of level measurement. This article covers why temperature has this effect and how it can be reduced.
