Energy Meter

Product Details:

Product Detail :- The PolluWatt™ Duo II thermal  energy meter and totaliser successfully combines a high-performance energy meter and three integrated, freely programmable analogue outputs (0/4 – 20 mA) in one housing.

Use the PolluWatt Duo II  to complete the heat measuring point with almost all the usual volume measuring units and temperature sensors that are currently used in the field.

Depending on the type and size of the volume measuring unit foreseen, the valence of the incoming volume signal is programmed at the factory before delivery. For measuring points in which the volume measuring unit is built into the heating, PolluWatt Duo II can be acquired as a supply calibrated variant.

For cooling devices there is a variant with national cooling meter approval according to K7.2.

The PolluWatt Duo II is used for energy metering in split systems which are equipped with passive pulsed flow meters and 2-wire or 4-wire Pt500 temperature sensors. In most cases PolluWatt Duo II is used with the following flow sensors:

  • Register’s date of re-calibration
  • Record number and duration of alarm states

Specifications

PolluWatt Duo II is ideally equipped for use in demanding metering tasks, thanks to:

• The use for temperature-measuring purposes of a high-resolution AD converter (20 bit) designed with long-term stability in mind and equipped with self-calibration and filter functions
• Short counter-cycle (mains version: 1 s)
• The ability to use high-resolution mechanical or electronic flow indicators operating at pulse frequencies of up to 200 Hz (mains version)

Diavaso is a suite of apps for remote meter reading using smartphones or tablets. The Diavaso app suite consists of 5 individual apps; SensusRF Finder, Collection Station, Collection Mobile, Configuration & Service, and Data Logger. These apps can be used individually or in combination, depending on your requirements for remote meter reading (AMR) or small scale fixed network (AMI). The mobile applications run on an AndroidTM device and communicate with the meter via the SensusRF radio transceiver SIRT (Sensus Interface Radio Tool). The Diavaso apps are compatible with all SensusRF enabled meters and repeaters.

The Diavaso apps are designed to be used for meter installation, remote reading, maintenance and configuration of meters and repeaters. The Collection Mobile also includes a server based interface (web portal) for managing the meter reading workflow, reporting as well as data exchange with the billing system. See datasheet (LS7000) for detailed information.

Product Details:

Description:- The PolluTherm® integrator measures energy consumption in heating or cooling circuits. PolluTherm can also be used in combined heating and cooling systems where an automatic switch-over point stores heating and cooling energy in separate registers. This switch-over point can be changed in accordance with the heating and cooling system requirements even after the meter has already been installed (e.g., concrete core activation).
The novel casing concept of the PolluTherm offers two slots for upgrade with various modules (e.g., M-Bus or remote reading pulses) at any time for data communication and remote reading.

Benefits to you

• Simplifies stock-keeping;  input pulse values can also be programmed on-site (order variant without surcharge)
• Connects temperature sensors Pt 500 in four-wire technology for quick and economic extension of temperature sensor cable (standard)
