Flowmeter (for Sensitive Measurements)
MODEL RK 1450 SERIES
This top-grade high-precision area
flowmeter is a fruit of KOFLOC’s challenge to boost the general perception
currently conceived by people of 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.
– 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 laboratory
– For semiconductor manufacturing equipment
– For biotechnology industries
