INTRODUCTION

PORTAFLOW™ 216

The utilises Ultrasonic transit-time “Clamp-On” transducer technology.

Easy to operate, the Portaflow 216 features are as follows:

Large easy to read Graphics Display with backlighting.

•

Simple FAST TRACK set up procedure.

•

Simple to follow keypad.

•

IP55 electronics enclosure.

•

Guide rail assembly with chains.

•

Pulse Output or 4-20mA (optional)

PARTS AND ACCESSORIES

Connectors

There are four sockets on the electronic housing. Two for the transducer cable assemblies (Blue down/Red up), one for the pulse output, one for the PSU/charger unit and one for the optional 4-20mA output. Please specify 4-20mA output in your order so that it can be configured prior to dispatch.

Pulse Cable Connections

Pulse output – Centre (White) positive, Screen (Silver) negative.

4-20 mA Output connections (optional) only added to software versions 216-3 & 216-2

Charger

The charger is supplied with universal plug-in adaptors. When the instrument is charging, but switched off, the display reads ‘CHARGING flow mode and the battery charger is connected. When the battery charger is disconnected the display will show a % battery level in the flow mode.

(Use only the charger supplied.)

It also displays a battery and plug symbol. CHRG is displayed next to the word ‘Batt’ when in

’.

90Vac to 265Vac 47/63mhz @1.1A

Is supplied with additional plug heads for use Worldwide. The charger is rated

Battery Circuit

A battery management circuit controls the battery recharge. The circuit helps to prevent the batteries from being damaged through overcharging. The circuit automatically cuts off the high-level charge current after 4hrs, afte r which it will provide only a trickle charge. In operating mode a fully charged battery can maintain functionality for up to 8hrs depending upon the demand. A large percentage of the demand taken by the ‘Backlighting’ and whilst it is continuously enabled the operating life will drop to 4hrs from a fully charged battery. When in flow measurement mode the battery charge level is continually displayed as a percentage of full charge. When this indication reads approximately 40%, a warning message will appear on the screen. This indicates that there is only 30 minutes use left in the battery. The battery can be charged when the instrument is switched to the ON or OFF state.

See full instructions on charging and discharging the batteries on page 30-31.

Keypad

Programming is via a key tactile membrane keypad.

When measuring flow it is possible, by selecting keys 4, 7, 8, and 9, to change from one unit to another without the need to re-program. Additional key presses will adjust the time scale of the measurements. Example:

Press 4 for m/s, press 4 again for f/s

•

Press 7 for l/s, press 7 again for l/min

•

Press 8 for g/min, press 8 again for USG/min

•

Press 9 for m

•

There are some facilities that require the cursor to be moved from left to right. This can be done using keys 5 (left) and 6 (right). The pulse output, can only be activated in the flow mode (see page 12 – Pulse output key). 4-20mA(216-3 & 216-2 only)

/hr, press 9 again for m3/min, press 9 again for m3/sec

Transducers

The Portaflow 216 is supplied with one (matched) pair of transducers and a single guiderail to measure flow. The instrument selects the mode of operation (Reflex or Diagonal) dependant on the pipe size and flow velocity. The instrument can be used over a range from 50mm to 400mm. In Reflex Mode the transducers are positioned in the guide rail to assist correct alignment along the pipe axis, removed from the rail and attached to the pipe using the gull-wings and chains. The pipe is then measured and marked up and the transducer blocks are clipped to the pipe wall using a suitable amount of grease applied to the face of each transducer.

(Figure 4)

the transducers are

Separation Distance

The instrument calculates the separation distance when all parameters have been entered via the keypad. Also the instrument calculates the maximum flow velocity allowed with the standard sensors and indicates whether Reflex or Diagonal mode should be used.

Ultrasonic Couplant

Ultrasonic couplant/grease must be used on the transducer face to interface with the pipe wall.

Fluid Types

Portaflow 216 is capable of measuring clean liquids or oils that have less than 2% by volume of particulate content and air bubbles. During the set up procedure the user is prompted to select from a list of liquids, which include water and oils. Applications include - river water, seawater, potable water, demin water, treated water, effluent, water/glycol mixes, hydraulic oil, diesel oil and most chemicals.
