Vane wheel flow meters designed as insertion probes are suitable for both fixed and portable applications for flow measuring in gases and liquids / water, as well as for Ex requirements (ATEX, CSA). PROBE ZSR25 ... ZG1/ZG2 - WITH +/- DIRECTION SENSING - WITH CONNECTION CABLE: Cylindrical vane wheel sensor / insertion probe with probe diameter 25 mm and +/- direction sensing. Probe materials: aluminium, stainless steel or titanium. Working temperature range up to +240 °C. Suitable for fixed measuring of actual flow velocity v [m/s] and flow rate V/t [m³/h, l/min] in clean gases and liquids, briefly also in particle-laden mediums. They are extendable and therefore practical for applications in free or pipe flows, where the +/- flow direction is to be measured as well. We recommend our TSR probes for aerodynamic analysis in free flows, where the direction of flow is unknown. MEASURING RANGE: 0.4 ... 120 m/s in air/gases ; 0.04 ... 10 m/s in water/liquids. PRESSURE RESISTANCE: up to 6 bar / 600 kPa overpressure. These flow quantity meters designed as probes can be used in pipes or ducts with an inside diameter equal to or greater than 40 mm and are anchored with a pressure resistant probe guide piece. Alternatively, these flow rate sensors can be manually operated for applications in fixed free flows for gases, water and in liquids or for measuring fluid flow. Probe extensions are available for deeper insertion of the flow sensors in the medium, for instance water, or for measuring gas emissions in chimney stacks and channels in incineration plants.
