Results

  • Coriolis flowmeter with no moving part offers higher plant availability and reduced maintenance efforts.
    • Best-fit instrument with intrinsic safety & providing reliable data and safety to the process

Challenge

Mechanical flowmeter with moving parts will wear over time and constantly need time and cost for maintenance.

Our Solution

Compact loop-powered Coriolis flowmeter, Promass E 200 with pipe spool could easily match the PD flowmeter face to face length without any pipe modification needed.

Coriolis flowmeters have been used for decades with great success. This measurement technology could simultaneously measure mass flow, density and temperature.

Benefits

  • Accurate mass flow measurement with no moving part.

  • Reduce maintenance cost and time – increase plant availability

  • Loop-powered coriolis flowmeter could reuse PD flowmeter cable to power up the flowmeter – no extra cable need to be laid

  • Safe plant operation with intrinsically safe design (Ex ia) flowmeter

  • Flowmeter with self-diagnostic according to NAMUR recommendation NE107 to prevent unplanned shut down

Process Description

The customer is one of the crude oil refinery in Malaysia. The supply and return of Liquefied Petroleum Gas (LPG) to and fro the LPG processing plant were measured with 3 units of positive displacement (PD) flowmeter. PD flowmeter is a volumetric flowmeter with moving parts subjected to wear hence influence the flow measurement accuracy. Usually filter is installed before the flowmeter and frequent cleaning is needed to prevent flowmeter clogging and causing production down time.
