µ-FLOW series L01
Mass Flow Meters / Controllers for liquids

General

µ-FLOW are Liquid Flow Meters (lfm’s)/Controllers (lfc’s) for ultra low flow ranges. The instruments operate on a thermal, thru-flow measuring principle. The flow meter can be connected to a control valve to form a closed control loop.

Lowest range 5 ... 100 mg/h
Highest range 0,1 ... 2 g/h (fluids with thermal properties similar to H₂O)

Note:
For higher flow ranges, Bronkhorst High-Tech offers the LIQUI-FLOW™ series.
Ranges: 0,1 ... 5 g/h up to 0,4 ... 20 kg/h H₂O-equivalent.

Flow control

Flow control is achieved by integrating a control valve onto the body of the Liquid Flow Meter. This control valve has a purge connection to eliminate air or gas during start-up. The electronic control function forms part of the normal circuitry in the meter.

Features

• No moving parts
• Thru-Flow measurement
• Attitude insensitive
• Fast and accurate measurement
• Negligible dead-volume (sensor: 1,5...33 µl)
• In combination with a control valve: continuous and stable control
• Analog or digital: RS232, Profibus-DP^®, DeviceNet™, Modbus or FLOW-BUS
• Stainless Steel sensor
• NEW: 1000 bar (15000 psi) LFM for 100 up to 450 mg/h FS (based on H₂O)

Applications

• Pharmaceutical industry
• Food industry (flavors, additives)
