Integrated liquid dosing systems.Mass flow metering and control experts Bronkhorst UK, have introduced a series of fully integrated Liquid Dosing Systems, covering an enormous flow range from a few nanolitres to 1000kg/hr and beyond. Fully factory assembled and tested, they are delivered as easy-to-use, compact systems, offering extremely high accuracy and virtually pulsation-free flow patterns, with single point responsibility for all components. Competitively priced, they offer a highly cost-effective, trouble-free solution for many dosing applications. Each integrated Liquid Dosing System consists of a proven mass flowmeter See flow meter. from either Bronkhorst's thermal mass Thermal mass, in the most general sense, is any mass that absorbs and holds heat. In the architectural sense, it is any mass that absorbs and stores heat during sunny periods when the heat is not desirable in the living space of a building, and then releases the heat during LIQUI-FLOW or Coriolis-type CORI-FLOW series, with onboard controlling function, a closely-coupled gear pump A Gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps however are also widely used in chemical installations to pump fluid with a certain viscosity. , liquid filter of the correct mesh type and size, a check valve to avoid backflow backflow /back·flow/ (-flo) reflux or regurgitation (1). pyelovenous backflow drainage from the renal pelvis into the venous system occurring under certain conditions of back pressure. and all interconnecting material. Bronkhorst will undertake all electrical and mechanical connection, testing and optimisation, including programming the integrated PID controller on the PC board of the flowmeter, which can be optionally equipped with various fieldbus interfaces. For small flow rates and low viscosities, Bronkhorst fits its own LIQUI-FLOW rotary displacement liquid pumps, which are virtually pulsation-free in operation, feature a stainless steel stainless steel: see steel. stainless steel Any of a family of alloy steels usually containing 10–30% chromium.

For applications requiring higher flow rates, higher pressures or aggressive dosing fluids, Bronkhorst employs HNP HNP Health, Nutrition and Population HNP Herniated Nucleus Pulposus HNP Host Negotiation Protocol HNP Hernia Nuclei Pulposi (Medicine) HNP Herstigte Nasionale Party van Suid-Afrika HNP Herenigde Nasionale Party micro annular annular /an·nu·lar/ (an´u-ler) ring-shaped. an·nu·lar adj. Shaped like or forming a ring. annular ring-shaped. gear pumps, for flows up to 70kg/h, and Micropump liquid gear pumps, for flows up to 1000 kg/h, both series again offering high precision dosing and pulseless delivery. To ensure safe operation and prolonged reliability, Bronkhorst enables the response alarms on either the LIQUI-FLOW or CORI-FLOW flowmeter, which will stop the pump unit when flow is not within pre-set parameters or if there is a blockage downstream. Both instruments can also be used as batch counters, with the desired batch programmed into the integrated counter limit value, so that the instrument stops the pump when the limit is reached, until the next batch is reset.
