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 M-60 Series low flow, flow switches monitor increasing and decreasing flow. They utilize a single moving part which responds to fluid (liquid or gas) flowing within a system. These switches are suitable for a wide range of applications in industrial, biomedical, and OEM products. The flow monitors operate only when fluid is positively established.
Fixed setting PTFE flow switch with in-line flow
The M-200 Series flow switches are engineered and field tested for sensing increasing and decreasing flow rates of gases or liquids. Pressure variation effects are minimal. This series features such versatility, economy, and accuracy that they can be used in virtually any application requiring fool-proof inexpensive flow detection.
The M-50 Series low flow, flow switches monitor increasing and decreasing flow. They utilize a single moving part which responds to fluid (liquid or gas) flowing within a system. These switches are suitable for a wide range of applications in industrial, biomedical, and OEM products. The flow monitors operate only when fluid is positively established.
The COVOL oscillating piston flow meters is ideally suited for viscous fluids such as oils, waxes and polymers. The sensor is constructed in SS-316, PVC, PP and PTFE materials options. It can be easily cleaned and sterilized.
Malema's SC250 & SM250 model metal tube variable area flow meters are suitable for gases, liquids and steam flow measurement. It uses a robust metal tube construction with an optional plastic liner to handle tough and corrosive process fluids.
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.
