Mega System Lotus Isokinetic Data Processor

Lotus is a processor that carries out automatic isokinetic sampling when connected to Lifetek or Aster series samplers through a serial interface. It measures gas velocity with an L- or S-type pitot tube and thermocouple and calculates flow in the duct. It is also used for velocity and flow measurement in stacks and ducts.

• Complies with UNI EN 15259, UNI EN ISO 16911-1, UNI EN 13284-1 and ISO 9096.
• Includes three independent pressure sensors: differential, static and barometric.
• Offers a graphic display, permanent memory and USB data transfer.
• Customer, duct, sampling and audit records are kept.
• K, J or T type thermocouple and pitot options are available.

The instrument measures 220 x 105 x 45 mm and weighs 500 g; it is powered by a 12 V DC lithium battery or 230 V AC and supplied with a shoulder bag.

After the velocity profile in the stack is measured, Lotus calculates the appropriate nozzle selection and flow setting. When connected to an Aster or Lifetek sampler, it updates the setting automatically throughout sampling, eliminating the need for manual correction.

Tetra offers Lotus as a measurement set with an Aster sampler and pitot tubes. Checks and periodic calibration of pressure sensors and supply of parts such as sensors and batteries are carried out locally in Türkiye.
