OSGC type EP1

The core of our odorizing system type EP1 is a LEWA diaphragm pump. Application using one or two LEWA pumps, see pictures.


Odorization system

Our odorizing equipment works on a injection basis. The standard is that information about the current gas flow is  transmitted from the gas meter, gas converter or control system via pulses. It is also possible to transmit this information via the MODBUS communication.

The control system of the odorization station evaluates this information and activates the dosing device – pump. The dosing device conveys the set amount of odorant from the storage tank via the injection device into the gas flow.

The UMARS-MINI electronic control the individual components of the station, control, dosing, data collection and transmission. It is certified for placement in Zone 2 hazardous areas.

The odorization station is equipped with filters for capturing impurities in the odorant and also with a filter with activated carbon on the deaeration pipe. A level indicator is placed on the front panel in order to visibly monitor the amount of odorant in the tank, but also to verify the functionality of the dosing device.

The amount of odorant in the storage tank is recorded by an ultrasonic level sensor, which informs about the level status and the set limit values, i.e. about reduced and low level. The odorization station is shut down in the event of a low odorant level in order to prevent aeration of the station.

A flow meter fitted behind the dosing device indicates whether a dose has been performed. After the dose, the green LED diode lights up. If these doses are not detected by the flow meter in the interval of 10 doses, the control electronics will shut down the odorization station. The by-pass valve serves not only to test the dosed amount of odorant, but also to initially vent the entire odorizing device.
