Pulsar Flow Pulse PC Software

Description

Pulsar Flow Pulse PC Software users can see at a glance the flow rate in units of their choice, the application can be monitored in terms of signal strength and confidence, and the raw signal can be seen. The RS232 Modbus connection allows the Flow Pulse to be set up through an intuitive and straightforward set of parameters, while real-time flow information can be read and recorded.

Flow Pulse is simplicity itself to set up. All that is required once Flow Pulse is in position and powered is to provide the internal diameter. The rest of the setup process is all about options and the way that the information is presented and recorded, especially if multi-drop Modbus RTU is in use.

‘Signal Strength’ (see screen shot opposite) is a measurement of the total strength of the returning echoes from the interior of the pipe. ‘Confidence’ is, as the term suggests, a measurement of how sure Flow Pulse is of the measurement and is an indication of the consistency of the flow rate. Confidence will increase the longer flow continues.

Flow Pulse PC is free-issued with Flow Pulse and requires no further licensing or equipment to run, other than an RS232 cable (available from Pulsar if required).

Amazing new flow monitoring technology

Flow Pulse® is a major leap forward in flow measurement – no need to break into a pipe, or to get anycivils involved, just clamp a small sensor to the out-side of a pipe and get reliable, repeatable flow moni-toring straight away. Virtually no installation costs, no interruption to service, clean and simple.

Flow Pulse is simply fixed in place by a band (tools required = one screwdriver). A silicone coupling pad makes sure that the Flow Pulse makes a good acoustic contact to the pipe. Flow Pulse uses a novel spread spectrum analysis technique never before used in flow monitoring. It incorporates a radical new Digital Signal Processing (DSP) approach that gives exceptional repeatability.

Flow Pulse produces a wide ultrasonic beam that is refracted by the pipe wall, as well as reflected by suspended particles in the flowing media. Ultrasound is fired through the pipe wall at 90 degrees to the flow via a tangentially mounted high-output ceramic, then refracted at angles across the axis of the flow and subsequently reflected from bubbles, particles and vortices in all directions and at a wide range of frequencies.

The wide, refracted, ultrasonic beam maximises the ultrasound energy captured from flowing particles. These multiple reflections are received back into the unit via a second high perform

Software

To accompany Flow Pulse®, Pulsar have introduced Flow PulsePC,software to control, set up and monitor Flow Pulse
