Introduction
Censeo product family is the latest offering from Secure Meters aimed towards measuring and monitoring
critical pump/ hydro-turbine/ blower performance parameters with high accuracy in commercial and industrial
pump/ hydro-turbine/ blower installations.
Censeo –
•
Monitors and displays pump/ hydro-turbine/ blower operating parameters in real time with the help
of temperature and pressure sensors and a power meter.
It measures suction/ inlet pressure, discharge/ outlet pressure, suction/ inlet temperature and
differential temperature; and reads motor/ generator parameters such as voltage, current, drive
power/ generated power, power factor and frequency through interfaced power meter to calculate
the pump/ hydro-turbine/ blower performance parameters such as efficiency, flow rate and total
head. These parameters can also be read by a computer over RS485.
•
Is run time configurable through a software tool called Pump Test 9. This software is used to
configure essential information and parameters such as Censeo time, communication, displays,
historical data, analogue outputs, alarms and relays. Besides configuring Censeo, Pump Test 9 is
also used for viewing online data, reading historical data, alarms logged and transactions from
Censeo. (refer to Pump Test 9 help for details)
