Metering pump with automatic vent

22 May, 2008 | Supplied by: ProMinent Fluid Controls Pty Ltd

Gas-emitting media in metering applications can often reduce pump output or even prevent the pumped medium from being delivered. To avoid this situation, the pumps generally need to be bled manually in such applications. This procedure can be performed simply, conveniently and safely by the delta diaphragm metering pump with the new venting module.

Mass flowmeters

23 November, 2007 | Supplied by: AMS Instrumentation & Calibration Pty Ltd

The ST series flowmeter is designed for rugged environments typically found in the oil/gas, chemical, electric power, pulp/paper and wastewater treatment industries and applications. Its no moving parts, non-clogging flow sensing element provides direct mass flow output and features built-in temperature compensation. It is suitable for use in a wide range of process and plant gas applications, including compressed air, hydrocarbon gases and inert gases. The ST98 flowmeter has a reliable thermal mass flow sensor in a smart electronics package. It operates over a wide flow range from 0.21 to 172 NMPS in air with a standard flow accuracy of ±1% of reading, ±0.5% of full scale. It is suitable for a wide range of air/gas flow measurement applications, including natural gas or methane monitoring, compressed air metering, industrial HVAC systems, nitrogen blanketing and combustion air.
