Litre Meter ships chemical injection flowmeters

Litre Meter has announced that it has shipped more than 100 chemical injection flowmeters to Flutrol Com.e Controle de Fluidos Ltda in Brazil.

The meters are for use on a floating production unit (FPU), P56, owned by Petrobras, and to be located in the Campos Basin, off the coast of Brazil.

The meters are all of Litre Meter's range of VFF positive displacement meters adapted to suit the Petrobras specification including head mounted instrumentation in an EExd enclosure certified by Inmetro and providing a 4-20mA output signal with HART protocol communication.

Litre Meter said the meters are ideally suited to the oil and gas market as they are tolerant of both particulate and pulsating flows.

Charles Wemyss, owner and engineering director of Litre Meter, said: 'We have been able to offer a single product family to provide measurement of the different injection chemicals from hydrate and wax inhibitors to anti-biofouling ensuring oil in pumped in good condition.

'The units all use a common "top box" housed in an EExd explosion proof enclosure compliant with US and Brazilian regulations with rate and total display, as well as HART protocol.' He added: 'The VFF rotary piston flowmeter is designed for low flow chemical dosing.

Typical applications include methanol, scale inhibitor, corrosion inhibitor, de-emulsifier, O2 scavenger and wax inhibitor.

'The positive displacement type flowmeter is preferred to the turbine principle as it enables the meter both to measure high and low viscosity fluids and to track pulsations in the line.' The latest shipment of chemical injection flowmeters follows previous contracts to supply flowmeters for the P51 FPU and to a chemical injection skid builder in Houston, USA for similar equipment for the P52 and P54 platforms.
