Following the UK government’s decision to fund a network of 15 hydrogen refuelling stations by the end of the year, and Toyota’s launch of its hydrogen fuelled Mirai car in Europe, a new flow meter has been introduced to the UK by Litre Meter.

Hydrogen is pumped at very high pressures and its flow measurement needs to be extremely accurate, so there is a requirement for a robust and accurate flow meter that can operate over a variety of flow and temperature ranges.

Kem Kueppers Elektromechanik in Germany has developed the TCM 0450 Tricor Coriolis mass flow meter for clean energy fuelling station concepts, in particular hydrogen stations, which is available in the UK through flowmeter specialist Litre Meter.

The TCM0450 is constructed to work at a 1,050 bar design pressure with threefold safety factor and with integrated pressure and temperature compensation over the entire pressure and temperature range. Particular attention has been paid to the effects of hydrogen embrittlement and the selection of materials to avoid it.

The key benefit of the TCM 0450 is its high precision measurement during hydrogen refueling.

The full range of Tricor Coriolis mass flow meters offers a measuring accuracy of between+/- 0.10% and +/- 0.15%, even in long-term operation.

Litre Meter CEO Charles Wemyss said: “Litre Meter’s strength has traditionally been in flowmeters for particularly demanding situations, often with meters almost custom-designed and built for particular applications. Tricor Coriolis technology gives our customers access to a wider range of accurate and robust meters than previously available, which meet the needs of a vast range of industry applications.”
