Be better able to undestand the perfomance of a hydrogen flow meter

GM Flow公司设计了一种氢气流量计，并对其进行了流量测试，以验证该流量计的性能参数和精度。试验结果表明，可以达到并保持设计的工作压力、流量范围和精度。该流量计产生的系统压降明显小于竞争对手的流量计。该项目证明，该设计在不断增长的氢市场中具有非常良好的商业化基础。氢计量仪正在积极推广，并在租赁的基础上有了商业应用。在通过流动回路测试生成的测试数据中，在仪表的整体性能范围内的一个位置观察到一些特定的异常。通过测试产生的整体性能信封被认为是商业上可接受的。为了完整起见，必须对仪表运行包络内的特定局部异常进行充分调查。该项目将允许以详细和全面的方式调查和消除性能信封中的异常情况，以及测试仪表组件设计修改。仪表组件设计修改纳入了新的想法，以实现最准确，成本效益和环保的仪表设计，无论是制造和操作。

GM Flow designed a hydrogen gas flow meter, which was flow tested in order to verify the meter's performance parameters and accuracy. The tests confirmed that the as-designed operating pressures, flow ranges and accuracy could be achieved and maintained. The meter produces a system pressure drop which is significantly less than that of rival flow meters. The project proved the design had a very sound basis for commercialisation in the growing hydrogen market. The hydrogen meters are actively being marketed and have had commercial applications on a rental basis.Within the test data generated via the flow loop testing, some specific anomalies were observed at one location within the meter's overall performance envelope. The overall performance envelope which was produced via the testing is considered to be commercially acceptable. In the interest of completeness, the specific local anomalies within the meter operating envelope must be fully investigated.This project will allow investigation and negation of the anomalies in the performance envelope, as well as testing meter component design modifications, in a detailed and comprehensive manner. Meter component design modifications incorporate new ideas to achieve the most accurate, cost effective and environmentally friendly meter design, to both manufacture and operate.
