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 CMFC-5000 Integrated and Compact Coriolis Flow Controller controls liquid and Slurry flows up to 5000 grams per minute to within 1.5% accuracy of the set point, while providing a quick response time of within 2 seconds for consistent control. Mass flow measurement is fluid independent.
The M-2700 series is an integrated flow meter in a small package. It utilizes transit-time ultrasonic technology to determine flow rate and the latest high-speed digital signal processing (DSP) technology to provide a cost effective flow measuring solution with no compromise in performance.
The CPFM-8800 Series is a family of advanced Coriolis flow meters fabricated exclusively from PFA polymeric material for measuring liquids in high-purity semiconductor, biopharm and other applications that require all-PFA wetted surfaces and provide a Mass Flow Rate, Total Mass and Temperature output with accuracy ±1% of reading.
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.
The M-701 offers low cost flow monitoring with a variety of switch actuation points and low pressure drop. M-701 is designed for ease of maintanance, as the bonnet and shuttle can be removed, leaving the housing and pipe work connections intact. All wetted parts are
polypropylene or stainless steel, making this switch ideal for a wide range of chemical and temperature requirements.
