LIQUI-FLOW®  Series L10/L20

The digital LIQUI-FLOW® Mass Flow Meter was designed to cover the range between 5 and 1000 g/h (Full Scale) in a compact instrument with a fast response. The Flow Meter is basically a stainless steel tube without any moving parts or built-in obstructions. The heater/sensor assembly is arranged around the tube and, by following the anemometric principle: a constant difference in temperature (ΔT) is created and the energy required to maintain the ΔT is dependent of the mass flow rate. Due to the benefits of the unique patented sensor, the fluid will be warmed to a maximum of 5°C, thereby making the L10/L20 series suitable for fluids with low boiling points.

 

μ-FLOW series L01

Today's market for liquid flow meters tends to develop into the very small flow ranges - even into nano-flow ranges. The result of the new development is a small, compact instrument with ranges from 25...500 nanolitres per minute (1.5...30 mg/h) up to 0.1...2 g/h. Fields of application include Semiconductor industry, HPLC applications, Chemical industry, Food & Pharmaceutical industry, and Analytical laboratories.

 

CORI-FLOW® series direct mass flow meters and controllers

 

CORI-FLOW® utilizes a patented, advanced Coriolis type mass flow sensor to achieve unsurpassed performance, even with changing operating conditions in pressure, temperature, density, conductivity and viscosity. The instruments are offered as separate flow meters or with close-coupled control valve or pump, thus constituting a compact Coriolis-type mass flow controller. There are 4 models with overlapping nominal flow ranges from 200 g/h up to 600 kg/h (full scale value), each offering "multi-range" functionality: factory calibrated ranges can be rescaled by the user, maintaining the original accuracy specs.

 

 

Liquid Dosing Systems

The concept of using a straight forward Mass Flow Controller is simple and economical. It requires a certain head pressure, which can be achieved by pressurising a vessel filled with liquid, for instance by using an inert gas blanket. In some applications this method is not possible or not recommended. The alternative of using a pump for fluid transfer seems logical, but was not always advisable because of the pulsating flow pattern of most low-flow pumps.

 

Bronkhorst offers Liquid Dosing Systems to cover their liquid flow range of 20 mg/h up to 600 kg/h. Each Liquid Dosing System consists of a flow sensor of the LIQUI-FLOW® or CORI-FLOW® series with controlling function, a gear pump, a filter, a check valve and all interconnecting material. Furthermore, Bronkhorst will take care of electrical and mechanical connection, testing and optimization including the PID-integrated controller. In addition to the Bronkhorst LIQUI-FLOW® Pump for small flow ranges, a complete series of pumps is available for those applications which require higher flow rates, higher pressures, wide control ranges or aggressive fluids.
