High Cost-Performance
The MICROSTREAM Sensor was developed to meet the fluid engineering demands for a precise, easy-to-use flow-rate control and monitoring system that can be applied to a wide range of fields.
The MICRSTREAM Series meets the needs of vanguard R&D departments across the face of industry.
What's more, if you have found micro FlowSensor instrumentation to be prohibitively expensive in the past, you will be amazed at the ease and economy with which the MICROSTREAM system can be adopted. The proliferation of micro computers has created an increased demand for reliable, and economical systems which are easy to operate. The MICROSTREAM Sensor for the control and monitoring of fluid flow-sensor has met this demand, and has revolutionized the fluid instrumentation industry in the process.
Applications
- To control kerosene burner combustion for efficient fuel control
- To indicate the fuel consumption rate and ‘remaining fuel’ of internal combustion systems
- To control the flow for chemical feeder systems
- To measure the flow of liquid cosmetic products,etc.
