Kofloc RK 1450 Series High Precision Flowmeter
This top-grade high-precision area flowmeter is a fruit of KOFLOC’s challenge to boost the general perception currently conceived by people of the flowmeter of being a “mere yardstick” into a new conception that a flowmeter is a “precision instrument.” This flowmeter particularly features its uniquely precision-formed glass tube and ultra-precision ball float.
Features
- Capable of measuring ultra-minute flows
Can measure a wide range of flows from ultra-minute flows of 0.5-3ml/min to flows of 3-30l/min. - High precision measurement
High precision measurement of flows is available up to±2% of full scale (standard specification)or to±1% of full scale(optional specification). - Wide variations
A broad range of variations is available in total length, materials of construction, flow rate, pressure, scale, and so forth to meet diverse applications from a variety of fields. - Capable of measuring all kinds of gases
Practically all kinds of gases can be measured, not to mention those standard(Air, N2, O2, H2, He, Ar and CO2). - Measurement of water flows also possible
Measurement of full-scale water flows not exceeding 1l/min is also possible. (Dimensions may vary depending upon the specified maximum flow rate.)
Applications
- For integration into your equipment panel
- For flow inspections at a laboratory
- For semiconductor manufacturing equipment
- For biotechnology industries
