Product Description

Due to the current (March 2020) situation regarding COVID-19 and the call for the manufacture of ventilators, there is a high global demand for both flowmeters and ventilation test instruments. We currently have a lead time of 1-2 weeks, but this is subject to change based on demand on and stock levels. We ask that you place your order as soon as possible to be placed in the queue for this equipment. Please contact us for further information.

These Mass Flow Multi-Meters provide a bi-directional flow rate measurement with 2% of reading accuracy across a wide flow range. Integrated temperature and pressure sensors compensate flow measurements to provide mass flow readings independent of temperature or pressure. In addition to temperature and absolute pressure measurements, a built-in totaliser measurement enables users to make volume measurements as a running total. 5320 models come with a standard accessory kit.

5320 models include integrated humidity and differential pressure sensors. The humdity sensor provides relative humidity readings and its measurements are used to compensate the flow measurement for humidity effects. The added pressure sensor enables users to measure the pressure differential of flows at the flow meter or at any point in the line. In addition to the totaliser, these models can make precise volume measurements through the use of flow or pressure triggers. The 5320 models also include a built-in data logger that can save synchronised measurement data directly to the flow meter.

Easy to operate

View up to four readings simultaneously from the colour touchscreen display. Quickly and easily configure measurements and device settings directly from the flow meter. Connect and operate the gas flow meter through your PC with FLO-Sight software to take advantage of advanced data display and device settings options.

Fits your application

The Flow Meters are lightweight, compact, and can measure across a wide dynamic operating range. The 5000 Series Flow Meter also incorporates configurable tube end adapters, touchscreen control, and multiple mounting options. Whether measuring gas flows in a laboratory, manufacturing, or service setting, the 5000 Series Flow Meter can adapt to fit your unique application.

Proven Performance

5000 Series Flow Meters utilise a proprietary platinum film sensor with proven performance that’s been relied upon for more than 35 years. The flow sensor design is optimised for applications where high accuracy, fast response, and low pressure drop are performance musts. Fast sensor response ensures accuracy in fluctuating flows and is ideal for closed-loop control systems and integrated volume measurements. The low pressure drop of flow meters minimises flow circuit back pressure and its impact on the system.
