Achieve Process Accuracy with Malema Flow Measurement and Control


Is Your Flow Measurement Technology Delivering the Accuracy Your Process Demands?

Flow is critical to your industrial process, and the consequences of inaccurate flow measurement escalate fast. Too much, too little or inconsistent flow can diminish yield, compromise product quality, damage equipment and jeopardize safety. Preventing these risks starts with precise flow measurement and control technology.

For over 45 years, Malema has engineered flow measurement and control solutions built for the realities of industrial process environments, delivering the accuracy and process visibility operators depend on to stay in control.

Precise Flow Measurement and Control

Industrial processes rely on flow behaving within defined parameters. When it doesn’t, the impact can be immediate. Coolant stops circulating, lubrication drops below threshold or chemical dosing drifts. Other times, the effect is not felt until it surfaces further down the line as off-spec output or product quality issues. Either way, the cost of operations is high.

Malema flow measurement and control technology — flow switches, flow meters, flow controllers, excess flow valves and more — help industrial operators keep critical processes running safely, efficiently and reliably.

Industrial Application Expertise

The Malema engineering team has spent decades working directly with operators and systems designers, evaluating process requirements and designing advanced flow measurement and control technology. Whether you are selecting a flow instrument for the first time or replacing an existing one, Malema can help you identify the right technology for your specific process.

Applications

  • Gas Analyzers and GC Sampling Systems – Malema flow switches ensure carrier gas reaches the analyzer at optimal flow rates. The M-VF Series Excess Flow Valve provides automatic shutoff in the event of line or fitting failure.
  • Compressor Lube Oil Circuits – Malema flow switches monitor lube oil flow to bearings, gears and couplings, triggering an alarm if flow drops below required levels.
  • Cooling Water Circulation Systems – The M-1000 Paddlewheel Flow Meter provides accurate, real-time flow measurement to maintain cooling system performance.
  • Air Conditioning and HVAC Compressor Systems – Malema flow switches verify cooling water circulation before compressor motors start, protecting equipment from insufficient flow.
  • Welding Systems – Malema flow switches detect insufficient shield gas and coolant flow in automated and robotic welding systems, signaling your PLC before damage occurs.
  • Vacuum Pump Bearing Purge Systems – The M-60X Explosion-Proof Flow Switch monitors nitrogen purge flow in bearing chambers, shutting down the system automatically when flow drops below threshold.
  • Chemical Dosing and Injection Systems – Malema flow switches detect low flow rates in chemical injection systems, providing proof of dosing and shutting down the system when flow drops below acceptable levels.
  • Water Purification and Treatment Systems – Malema flow switches detect incoming water flow for treatment processes, with relay output used to control UV systems or chemical injection pumps.
  • Hydrogen Systems – The M-VF Series Excess Flow Valve delivers fully mechanical, automatic shutoff protection for hydrogen systems in refinery, electrolyzer and fuel cell applications.
