GENERAL DESCRIPTION
Components
The
INSIGHT Portable Flow Tester
consists of the following components:
Case
Digital Flowmeter Display
Battery and Charger
Flow Tube(s)
Paddlewheel Flow Sensor and Sensor Housing Assembly
Cables
Case
Mounted inside the Pelican case is a panel that has a digital flowmeter display
module, power switch, low battery indicator, and input cable connectors installed.
The case also houses a rechargeable battery and an AC charger/power supply. A slot
cutout in the front panel allows for the storage of cables. All controls and indicators
are located on the front panel. (Refer to Controls and Indicators.)
Digital Flowmeter Display Module
The flowmeter display module contains a digital display, two buttons and an LED.
It also houses the electronics and programs that are used to operate the portable tester.
The programs are accessed and inputs are made by using two buttons on the front of
the display module.
Battery and Charger
The battery and charger used in the tester is a maintenance free, sealed lead acid
battery. If any problems occur with any of the charging circuits, or if it is found during
a test that the battery is not charged, it is possible to power the unit directly from either
a 120 VAC or a 12 VDC source. (Refer to Power section.)
Flow Tube(s)
The tester can store in memory calibration data for up to six flow tubes. Each
flow tube will have a mount for a paddlewheel flow sensor.
Paddlewheel Flow Sensor
The flow sensor provides an input signal to the display module that is proportional
to the flow rate through the tube. It is mounted in the discharge end of the tube. The
electrical connector is waterproof and molded into the flow sensor housing.
