Chemical injection – flow monitoring

Request a Quote

Corrosion inhibitor and Scale inhibitor together with Methanol are routinely injected into crude oil reservoir rock to maintain oil flow and protect pipelines. To overcome the enormous wellhead pressures the chemical injection systems typically operate at 300 – 400 Bar and inject the chemical at very low flow rates. It is essential to monitor the pumps for any loss of flow but there are very few devices capable of detecting such low flows and such high pressures.

The FLT93L is used extensively for monitoring chemical Injection pumps and is designed for operating pressures up to 700 Bar and can provide reliable low flow alarms down to 0.15 Litres per hour. The FLT93L is both ATEX Exd and SIL2 rated.
