RPFS-type paddlewheel flowsensors

 

Remote monitoring and control of playing field and parkland irrigation

E State Automation, a Sydney-based telemetry engineering company,  has selected ManuFlo’s Roto Pulse Flow Sensor to use with their “PlayState” remote management system for playing fields and parklands.  Over 20 units have been installed.

With the monitoring of flow at an irrigation pump header tank location, there is typically no power available. The most cost-effective and efficient solution was to use a ManuFlo RPFS-L sensor, which has inductive coil low current pulse output for use with battery-powered devices.

 

 

E State’s “PlayState” system offers councils an integrated management solution, enabling the  remote monitoring and control of irrigation, lighting and access of their park sites directly from an office desktop computer.  Communication with each park site for the scheduling of control operation is via the internet. Alarming of fault conditions at the park site is via SMS. Sporting Clubs can also use SMS to control individual park lighting.

The technology has been embraced by a number of Sydney Councils, as it provides a powerful management tool that saves council significant time, energy and money in the management of its assets. In particular, the improved monitoring of the water usage (and possible leaks) has lead to significant savings of this important resource.  

The MRP20 and MRPU-type water flowmeters are now manufactured with a new style screw-on Locking Ring that is simpler to fit and remove, making it easier to access the flowmeter internal calibration adjustment controls.

The MRP20-type water flowmeters now have a slimmed-down flowtube (same connection ends), resulting in a slightly lower weight unit.

ManuFlo’s RPFS-type Rota Pulse Flow Sensors are a simple and cost-effective solution for medium to high flow measurement applications. The sensors are a paddlewheel insertion type, and come in 3 model variants:

· RPFS-P with plug-in cable, for transistor pulse connection;

· RPFS-H for hot liquids to 120 ºC; and

· RPFS-L for use with battery-operated devices;

all of which insert directly into a large range of pipe adapter fittings, covering standard pipe sizes 15 to 150mm.

With only one moving part, limited intrusion into the pipe, and flow-through design, the RPFS allows accurate measurement with virtually no headloss. It is used in a large variety of applications, including measurement of water in concrete batch plants, measurement of petrol/diesel, water irrigation, salt water, chlorinated water and countless other low viscosity liquid measurement processes.
