The Superstatic fluid oscillator measuring principle, used with the heat meters from Sontex, guarantees a high measuring accuracy and measuring durability. This fact was proved with top marks during the last heat meter tests of the German District Heating Association.

Now Sontex presents as a world innovation the small fluid oscillator heat meter Superstatic 449, an innovation with all known advantages of a Superstatic heat meter. The Superstatic 449 is a compact heat meter with MID homologation according to EN 1434 class 2 that perfectly complements the existing mechanical compact heat meter Supercal 539 (qp 0,6 – 2,5) and the static heat meter Superstatic 440 (qp 1 – 1500) at small flows.

The Superstatic 449 is offered for flows of qp 0,6 – 2,5 and can also be used as a cooling meter thanks to the waterproof design. The small fluid oscillator works without restriction in all mounting positions
horizontal, riser or downward flows. The Superstatic 449 can easily be integrated in existing or new heating or cooling installations thanks to the comprehensive communication and expansion possibilities that the device offers and the complete data package like set day values, monthly values, average values, maximum values of flow, power, temperature and tariff functions. The Superstatic 449 also offers communication modules of M-Bus, Radio, RS-232, GSM and LON.
The Superstatic 449 ’static’ flow meter is EN1434 Class 2 Approved and is therefore compliant to the new Department of Energy & Climate Change RHI (Renewable Heat Incentive) scheme.

GWFcoder® technology:

Transfers the effective meter reading. The readout value in the billing system and the invoice are the same as the meter reading.

Pulse transfer:

The potential sources of error for a reproduced meter reading with pulse transmission are:

• Bouncing
• Backflow water
• Temporary signal interruption
• Double pulses
• Incorrect pulse value

The readout value in the billing system and the invoice may differ from the meter reading.

GWFCoder Applications

Wireless pit readout

Meter with GWFcoder® register, IEC interface and GWF radio module (type RCM-PI) is read out by radio using a mobile infrastructure.

GWFRead Mobile – Wall pad reading

Encoder meters with a wall pad can be read without entering the property by means of an inductive wall pad. The meter data is then automatically assigned to the customer. The meter readout device then transmits this data wireless via Bluetooth to the Mobile readout
device.

M-Bus remote reading

The meters with GWFcoder® registers and M-Bus interfaces are connected to an M-Bus remote reading system. This ensures that the meter data is transferred directly via an M-Bus data centre or level converter to a PC where the data is further processed.

Mobile on-site reading

■ Direct or outside wall readout via the inductive interface; transmission distance of up to max. 150m

■ Outside wall readout via the CL interface without access to the measuring point; transmission distance of up to max. 150m

■ Mobile «walk-by» meter reading or «driveby » meter reading from a moving vehicle without access to the property

Remote meter reading

■ The GWFcoder® technology enables the combined remote reading of water, gas and electricity meters

■ Depending on the interface at the communication unit (e.g. modem), various interfaces (interface converter) are available to integrate the GWFcoder® water and gas meters in the remote meter reading and to read out the meters with addresses according to IEC standards

GWFCoder Variants

The metering application dictates which unit is the most suitable for any installation. Suitable units are shown below for domestic and bulk, gas and water metering applications.

GWF Coder Technology

In the GWFcoder® system, the individual rollers of the mechanical register are read out optoelectronically. The position of the various long asymmetrically arranged slits in the roller counters is scanned using 5 light barriers (light-pipe transmitter and receiver).

The light barriers are implemented with phototransistors. LEDs, and light conductors, which are all consecutively scanned and evaluated. The precisely defined position of each individual roller counter is encoded as an absolute roller counter reading and read out as a part of the protocol via the GWFcoder® interface.

This functioning principle is patented by GWF. The GWFcoder® interface, compared to a meter with a pulse output, has an incomparably higher level of information content and readout accuracy. A GWFcoder® register does not require a battery, which, in turn, does not compromise existing revision cycles. The readout device supplies the power for the readout.
