Features

Rosemount™ 4088 MultiVariable™ Transmitter
  • Modbus transmitter allows multivariable measurements in combinations of differential and static pressure and temperature
  • Primary elements available as assemble-to options for simple installation and commissioning
  • Optimized sensor technology captures large fluctuations in flow rate that commonly occur in oil and gas production applications
  • Enhanced for flow is a ±0.05% of reading specification for increased accuracy
  • LCD display provides data right at the measurement point for further insight into the process
  • Callendar-Van Dusen sensor matching improves temperature accuracy enabling best-in-class flow calculations
  • Reverse wiring protection guards the device from incorrect wiring
  • All-welded, SuperModule™ design offers industry-leading accuracy in harsh environments and applications
  • Low power consumption helps reduce the size and amount of solar panels and battery banks for cost-efficiency
Rosemount™ 485 Annubar™ Primary Element
  • Patented T-shape sensor creates a fixed separation point for DP signal improvement over a wider flow rate
  • Sensor stagnation zone positioned to reduce noise, measurement inaccuracies and keeps particulates from clogging
  • T-shape design offers very low permanent pressure loss
  • Integral thermowell adds process temperature measurement without additional pipe penetrations
  • Lightweight design at large line sizes provides a cost-effective primary element solution
