TTFM 1.0 Transit Time Flow Meter

Can I change the length of the sensor cable?

Yes. Technological advances in Greyline Transit Time design allow cable lengths up to 250 ft (75 m).
Extended cable (Greyline Option DXC) should be installed in rigid or flexible conduit for mechanical
protection. Use only Greyline shielded coaxial pair (RG174U) cable. BNC coaxial connectors (TV cable
type) are not recommended for cable splices.

Does the TTFM 1.0 require periodic recalibration?

TTFM 1.0 calibration does not drift over time. The solid state sensor has no moving parts to wear and
affect calibration. All Greyline timing/counting circuits use crystal-controlled frequency references to
eliminate any drift in the processing circuitry.

ISO 9000 or similar quality management systems may require periodic and verifiable recalibration of
flow meters. TTFM 1.0 Flow Meters may be returned to Greyline for factory calibration and issue of a
new NIST traceable certificate. Refer to the ‘Product Return Procedure’ section of this manual for return
instructions.
