Volume Corrector EK220

CNEK22007.2.P05

EK220 PT500 with Range Volume converter with data logger function, consisting of a central unit equipped with a pressure sensor and a temperature sensor. With measuring range from 0.7 ÷ 2 Bar.

EK220 is a battery powered volume converter. The device detects low-frequency pulses of the volume of gas measured under operating conditions from a gas meter. It measures the gas operating pressure and temperature, calculates the compressibility coefficient K and the conversion factor C.

Using these initial data, it is possible to calculate gas volumes at standard conditions, flow rates under standard conditions and flow rates under operating conditions.

The volume converter consists of a central unit equipped with an integrated or external pressure sensor and a temperature sensor.

The sensors are permanently connected to the unit. The compressibility coefficient K can be programmed as a fixed value for all gases or calculated according to various methods.

Thanks to the four digital outputs, the flexibility of the data logging function in addition to the freely configurable serial interface and the availability of different communication protocols, the EK220 can be used for various applications in the field of natural gas measurement and its monitoring from the station .

Additional components for data retransmission and explosion-proof isolation of the interfaces and the intrinsically safe external power supply extend the range of possible uses of the converter.

In addition to the conversion of gas volumes and data logging, the EK220 can be used for flexible recording of various measured values and, in combination with a  modem or a remote data transmission unit (RTU), for system monitoring.

The device is equipped with two additional digital inputs, which can be used to record and monitor the signaling sensors, such as the safety shut-off valves of the pressure regulators and the differential pressure switches of the filters, or for a simple door contact. The signals emitted by these sensors can be saved as an event in an archive and automatically retransmitted in the form of a text message or e-mail via a connected modem.

Optionally, the volume converter can be equipped with a second external pressure sensor which allows to detect the pressure at the inlet or outlet of the measuring system or to monitor its limit values.
