ELCORlite

The new series of gas volume correctors in the group of ELCOR has been expanded with a new ELCORlite device. This corrector offers a powerful solution with a fixed configuration for commercial gas metering purposes.

The ELCORlite gas volume corrector is a meter designed to convert the volume of gas measured under operating conditions to the volume under basic conditions.

Information about the flowed amount of gas is read through the pulse outputs of the gas meter. The gas temperature and the gas pressure are measured by integrated transducers. The degree of gas compressibility is calculated by the instrument according to conventional methods or uses a constant value.

Device description

The ELCORlite is a single-channel gas volume converter powered by lithium batteries. Low-frequency pulse input is used to connect to the gas meter. The pressure measurement is provided by the latest type of digital pressure transducer ELGAS EDT 125, which can be installed in the device as an internal or external design. Very wide measuring ranges (eg 80 - 2000 kPa) make it easier for the user to use the device in various types of measurements. The temperature measurement is again realized by a product of our ELGAS company. it is a temperature transducer with the name EDT 124. It is a new digital transducer with a semiconductor sensing element.

General properties

The devices are manufactured in three basic variants:
- with RS485 serial line
- with RS232 serial line
- without serial line
The design of the device with regard to less future scalability allows the customer a quick acceptable solution, which can be supplemented by 2G or 4G modems.

Communication

The device includes an optional integrated modem, which is available in variants that support all currently available networks, including IoT "Internet of Things" Narrow Band (NB) networks. In the future, the modem can be replaced at the installation site with a type that supports new modern technologies.
The modem is powered by its own lithium battery, which, depending on the selected modem, allows the modem to operate for up to 20 years (in LTE-NB networks).
