Edor

Odorization monitoring

Edor is the new sensor for the measurement of the amount of odorant in natural gas, used as remote station of survey. Two kind of odorant can be detected:

  • TBM: Mercaptans
  • THT: Tetrahydrothiophene

Edor employs electrochemical cells developed for this application, specific for each odorant.

Description

Edor is composed by

  • Microprocessor unit with modem GSM (opt.: GPRS, PSTN, FTP, mail);
  • Data acquisition system analyzer unit;
  • Electrochemical cell easily replaced (SNAP-IN);
  • Time controlled electrovalve that drives the flow of sample gas from main line to sensor.

Application

Edor can be installed in odorization plants (to verify the intake of the odorant in gas), characteristic points (to measure the true condition of network),at the end of network (to have the real situation in critical points, through all the day).

Accuracy

By mean of a SW correction in temperature, standard precisions reached is less than 15% , with no interfering substances. With the accessory Sampling System (option SS), precisions of 10% can be reached, thanks to periodic autocalibration carried out by means of a cylinder of calibration gas connected to a second electrovalve. Without option SS, it is however possible the periodic calibration (one person calibration).
