Equipment Pipel ine Inspect ion does not need to be installed on a run of straight pipework, as with other mag meters or vortex and ultrasonic flowmeters, but can be tucked away on bends or other confined spaces. With a footprint measuring just 100mm high x 100mm wide x 80mm deep, and weighing just 800g, the Miniature-Mag is housed in an IP67 rated dust- and water- tight housing, with the body available as standard in chemical-resistant PVDF or optional PTFE (Teflon), PVC or POM materials. A separate electronic display unit features a 2 line, 16 character text readout, giving push button control of batch counting, pre-set alarms, menu selection and other functions. The Miniature-Mag can also be specified as a flow controller, with an integral PID loop for control valve operation or direct pump control. Analogue, pulse, relay, RS232 and serial output connections are optional for interfacing with plant- wide control networks.

critical applications, such as brewing, food processing, the dairy industry, agriculture, cosmetics and chemical dosing in water treatment processes. In addition, current changes in the pharmaceuticals sector from batch to continuous production, with consequent downsizing of plant and pipework, make it increasingly relevant to that industry. Magnetic or electromagnetic flowmeters, commonly known as mag meters, are a common method of flow measurement, because they are easy to maintain, with no moving parts, and offer a high level of accuracy. Operation is based on Faraday’s law of magnetic induction, with the liquid acting as a conductor as it flows through the mag meter; this indicates a voltage proportional to the average flow velocity, which is picked up by sensing electrodes mounted in the pipework. Thus the fluid must be electrically conductive to induce measurable voltage, and most standard magnetic flowmeters operate with fluids down to around 15-20 microSiemens/cm (measure of conductivity).

In contrast, Bronkhorst’s compact magnetic flowmeter handles a minimum electrolytic conductivity of 5µS/cm as standard, with certain liquids measurable down to as low as 0.1µS/cm, or virtually non-conductive fluids. It also offers an accuracy of 0.2% of reading (with greater precision available if required), high speed response and a totally unobstructed flow path. Due to its compact size, the Miniature-Mag Bronkhorst’s ultra-compact electro- S S magnetic flowmeter can measure liquids with conductivity as low as 0.1µS/cm
