Natural gas is a valuable commodity and hence it requires highly precise measurement to avoid users from being over or under charged. Even small measuring inaccuracies can mean large discrepancies. Sick Automation’s FlowSic500 has impressed measurement professionals on field test installations via the features that give it a good lead over conventional gas meters.
The compact design saves space as the meter does not require straight inlet or outlet piping. The flowmeter measures fail-safe with battery backup in an intrinsically safe network operation with measuring components installed in a cartridge that can be replaced in a few simple steps. Alternatively, the meter can operate entirely from battery power for a period of up to 10 years in an energy efficient configuration. Due to its design, on-site recalibration of the FlowSic 500 is straightforward and quick – replace the cartridge and it is done.
The unit operates with no mechanical moving parts and is therefore not liable to wear, thus ensuring stable measurement certainty in the long-term. Sick Automation has developed ultrasonic transducers especially for this device that are not sensitive to interferences. The meter will not be harmed by overloading and it processes dynamic load changes without any loss in accuracy. The intelligent self-diagnostics immediately detect changes in measurement conditions, which might prevent the gas meter from achieving the specified accuracy. In addition, it incorporates a self-diagnostic system that ensures measurement accuracy and certainty for natural gas distribution with no risk that the gas flow will be blocked by the meter. Therefore, the device can be used in applications where a continuous gas supply is vital, for example in hospitals. Features of this ultrasonic meter for natural gas distribution include:
* Measurement certainty and safety of continuous gas supply.
* Reduction of installation costs due to integrated volume correction.
* Simple installation, compatible with conventional technologies.
* Simplified recalibration due to straightforward cartridge replacement.
* Reliable under dynamic load changes.
The FlowSic 500 is available in four meter sizes in common flange-to-flange dimensions and it complies with all relevant standards and regulations for natural gas distribution.
