TCS 700-45 Rotary Flow Meter


Model: TCS 700-45

The 700 series rotary flow meter has a simple and efficient meter design consisting of a housing and three rotors that rotate in unison within the measuring chamber. The absence of wear, from no metal-to-metal contact inside the chamber, eliminates any deterioration in accuracy and provides a long service life. The rotors are supported by bearings inserted into two bearing plates, where at the end of each rotor shaft is a timing gear. The timed rotation between each rotor is then transferred through the calibration adjuster to the register, which will then give a consistent and superior measurement of accuracy.

  1. Hi Expert,I have a early 2008 Mazda 3 TS2 diesel and have an iemertittnnt fault.Initially the engine would cut out shortly after starting when at low revs at a junction or roundabout. When it did so I turned the ignition key and she started. She would then run without any problems. This has subsequently changed, when she now cuts out it takes approximately 15 minutes (sometimes longer) for her to start up. Again when she starts she runs very well. The cutting out usually happens when she has started from cold although it happened once after I had driven for 20 plus miles, again at low revs.The last time the fault occurred was two weeks ago and it took a lot longer than 15 minutes for the car to start.Usually the time between the fault occurring is in the region of a week.I have taken the car to my Mazda dealer and to an independant garage neither of which can determine the cause of the fault.The car has done 55000 miles, when she cuts out there is no fault light illuminated on the dash and as far as I am aware no excessive smoke. She was serviced in November by the Mazda dealership and the fault started shortly after that.Any help you can offer will be greatly appreciated.Kind regards,Paul
