Siemens Measurements Ltd has developed the E6S, a single-chip-microprocessor domestic gas meter based on ultrasonic flow measurement. The meter has no moving parts, but is more accurate and stable than conventional diaphragm meters. It has a measuring range of 40 to 6,000 liters/hr. The measurement range is linear over a dynamic range of 400:1., The 'revolution' in domestic gas metering has started. Last year Siemens Measurements Ltd (SML) became the first company in the world to have a radically new design of domestic gas [...]

A fiberglass-reinforced resin composite (CR), already in use for fracture arrest in high-toughness ductile pipe, was evaluated recently for its ability to arrest cracks in brittle, low-toughness pipe. The 'Clock [...]

Excess-flow-valve (EFV) manufacturer UMAC Inc is trying to dispel some myths about its products by visiting gas utilities in the 'Flow Mobile,' a minibus equipped with latest in EFV technology. The bus features a compressed air product test area capable of simulating standard gas flow and systems upset conditions. EFVs have been assailed in the past for not being able to withstand snap-acting loads and system pressure drops. Federal legislation mandating the use of EFVs on new and retrofitted utility lines is in the offing.

The US gas grid should be able to meet increased demand for natural gas by the year 2000, according to a study by the Energy Information Administration. The report said that grids in some regions show great potential to transport additional volumes during off-peak periods. Volumes into the Midwest could be increased by 8.4 billion cubic feet a day (bcfd), since pipe line utilization there is only 64%. With 33.9 bcfd of interstate capacity, the Southwest has the greatest potential to export to other US regions., Interstate natural gas pipelines should be able to meet record U.S. natural gas demand by 2000, Energy Information Administration predicts in a new study. EIA noted the pipeline grid has [...]
