Edenbros is an Authorized, Stocking Distributor of Micronics Ultrasonic & Doppler Flow Meters
How Ultrasonic Flow Meters Work
Utilising advanced DSP technology, the
Portaflow 330 (PF330) is the latest portable flow measurement and
recording system to be added to the Micronics range of equipment.
The PF330 can display instantaneous fluid flow rates or velocity,
together with totalised values. It also incorporates a data logger that
can record up to 98k events which can be output directly to a PC or
printer or stored in the instrument’s memory for downloading at a later
time.
A variable current or pulse output, proportional to the detected flow
rate, is also produced by the PF330 to enable it to interface with a
range of external control devices such as those found in building
management or site monitoring systems.
The PF330 is very much designed with ‘ease of use’ in mind. An
interactive QuickStart menu, which simplifies system installation at any
suitable location, together with minimal set-up requirements, means that
the system can be installed and brought into service very quickly.
Furthermore, the application parameters for a particular site can be
saved to non-volatile memory and instantly recalled if a site is
revisited for monitoring at a later time – further reducing the set-up
time.
The flow sensors, or transducers, connected to the PF330 instrument are
attached to the outside of the pipe being monitored and provide totally
non-invasive flow measurement without disturbing the existing plant
equipment or process operation.
The maximum permissible pipe outside diameter depends on the type of
ultrasonic transducer in use:
Type ‘A’ transducer – usable with
pipes in the range 13mm to 115mm
Type ‘B’ transducer – usable with
pipes in the range 50mm to 2000mm
Type ‘D’ transducer – usable with
pipes in the range 1500mm to 5000mm (optional equipment)
The maximum permissible pipe temperature depends on the type of
ultrasonic transducer in use:
Type ‘A-ST’ (Standard) transducer
-20°C to +135°C
Type ‘B-ST’ (Standard) transducer
-20°C to +135°C
Type ‘A-HT’* (high temp)
transducer -20°C to +200°C
Type ‘B-HT’* (high temp)
transducer -20°C to +200°C
Type ‘D’* transducer -20°C to
+80°C
* Note that these transducers are not part of the standard Portaflow 330
kit but can be ordered as optional equipment
