Fluid material handling in the semiconductor industry requires processes that are accurate and repeatable, while maintaining the highest standards for purity and cleanliness. Reliability, quality, and productivity improvements improve throughput and give chipmakers an advantage in this highly competitive market. Malema’s high-purity solutions are engineered to improve process control through use of leading edge technologies.
Experienced in sensors, electronics, and process instrumentation, Malema incorporates groundbreaking state of the art technologies into every instrument.
The operating principle is based on a magnetic piston which responds only to the motion of fluids within the line, not to static or system pressures. In the presence of fluid flow, controlled movement of the piston actuates an external hermetically sealed reed switch. This switch can be used to actuate audible or visual alarms, as well as relays, or other controls.
Series 2000 glass tube variable area purge meters are available in 100mm, 150mm and 300mm tube lengths and with optional fine threaded regulating valve for precise flow measurement. They are suitable for gas and liquid flow measurement and control.
AD-15/ADI-15/ADT-15 series flow switches can be fitted with local flow indicators. AD series flow switches can be used for monitoring liquid and gas flows.
The M-10000 Paddlewheel flow meters are smaller, easier to install, and more accurate than ever before. Optional outputs such as 4-20 mA, 0-10 VDC, or pulse are available. In addition, M-10000 can also be used as an adjustable flow switch. These flow meters are available in both metal and plastic configurations.
