Emerson Rosemount 4088 MultiVariable Transmitter

The Emerson Rosemount 4088 MultiVariable Transmitter is a platform for upstream and midstream oil and gas applications, providing differential pressure, static pressure and temperature measurement from a single transmitter. The product’s extended range capability captures flow rate spikes above the upper range limit of the transmitter to account for flow that would have traditionally been missed.

The transmitter’s extended range capability delivers good measurement performance for plunger lift measurement applications over the life of oil and gas wells. Its sensor technology measures flow rate spikes while still achieving good performance over the typical operating range. By accurately measuring flow that is commonly missed, the extended range capability is said to ensure the accurate accounting of oil and gas production.

As wells mature and process conditions change, maintaining accurate measurement instrumentation is critical to well stakeholders and leaseholders. The transmitter offers stable performance over the life of the well, ensuring consistent production and minimising service and equipment costs.

The product provides a stable signal transmitted through Modbus, BSAP or MVS, resulting in good data accuracy and effective management of changing well conditions. The unit is typically integrated into a larger oil and gas production network by transmitting data to flow computers and RTUs. The device is designed to easily integrate with Emerson’s flow computer products, such as the ROC, FloBoss and ControlWave, but it can be used with any new or existing flow computer or RTU network that accepts Modbus input.
