Recommended for TMA: best sensitivity for liquid flows / suitable for gas flow – resists heavy coating
TMB: same as TMA but can be used with integral electronics up to +200 °C (+400 °F)
TMC: best sensitivity for air/gas flows – resists light coating
TMD: same as TMC but can be used with integral electronics up to 200 °C (+400 °F)
TMM: for direct mounting in “T” pieces on small pipe sizes – light coating
TMH: high temperature and pressure conditions – light coating
TML: for the detection, control of extreme low flows, resists light coating
➀Use remote electronics (TD2) for temperatures > +120 °C (+250 °F) up to max +200 °C (+400 °F) or sensors with heat extension
(TMB/TMD) when using integral electronics.
