Following increased demand for robust and accurate flowmeters for offshore oil and gas applications, UK flowmeter specialist, Litre Meter, has shipped its 3,000th offshore positive displacement (PD) meter. Recent shipments for offshore applications include a series of meters to be used subsea, on a variety of chemicals, over a wide range of flows at high pressure and calibrated at specific viscosities. For example, Litre Meter rotary piston flowmeters are part of systems used to control the amount of 'antifreeze' injected into pipelines at high pressure (430 bar) in subsea gas exploration on fields in the Caspian Sea and the North Sea.
