    Introduction Welcome Thank you for purchasing the Spirax Sarco MTI10 insertion or MTL10 inline Thermal Mass Gas Flowmeter and Temperature Transmitter. The Model MTI10/MTL10 is one of the most technically advanced flowmeters in the world. The MTI10/MTL10 utilize the same sensor and electronics. The MTL10 includes a company supplied flow tube, while the MTI10 is inserted into an existing pipe. Extensive engineering effort has been invested to deliver advanced features, accuracy measurement performance and outstanding reliability.

If zero flow can be established, the sensor does not need to be removed and the procedure can be done in the pipe. Alternatively, a Packing Gland Assembly can be used to remove the sensor from the gas stream to create a “no flow” condition. Note: If the Zero CAL-CHECK™ test is performed using the MTI10/MTL10 View™ Software, at the completion of the test, a Zero CAL-CHECK™ Certificate may be printed for a record of the test. This certificate will display a pass/fail result. Fig.

  • Page 67 Calibration With this configuration, the meter must be removed from the process, the test performed, and then the meter returned to the process after testing has been completed. Due to the high sensitivity of the PowerPro™ sensor, it is necessary to isolate the sensor once the meter has been removed from the pipe. Therefore, Spirax Sarco provides a sensor cover when the meter is shipped to the customer. An alternative to the sensor cover is to use a bottle or other closed container in order to isolate the sensor and achieve the "no flow" condition necessary to perform the Zero CAL-CHECK™ test.

Improper wiring connections for power and/or 4 to 20mA output signal. The MTI10/MTL10 require a separate power source for the main board and the two 4 to 20mA output signals.
  • Page 101 Check to ensure that this area is correct. Problems 4. Erratic flow reading especially a flow reading spiking high. This may be a symptom of moisture in the flow stream. MTI10/ MTL10 flowmeters are designed to work in relatively dry gas applications only. Contact Spirax Sarco to discuss resolutions to this problem. 5. Flowmeter is not responding to flow. This problem could be caused by a number of reasons: • Check to ensure adequate power is supplied to the flowmeter as described above. If things appear to be correct, an easy functional test can be performed.
