Calibrating the Condensate Flow Meter
Calibration #6: Calibrating the Condensate Flow Meter
1. Locate the 6mm tube coming from
D
P2 going inside the condensate vessel on top of EV2 and pull it out.
2. Confirm the 6mm tube is cut on an angle.
3. Replace tube back inside condensate vessel.
4. Ensure Steam QM-3 cabinet is level.
5. Locate the 6 mm tube coming out of the bottom of EV2.
6. Follow the tube to the end and remove it where it connects to the tee on the condensate return line.
Place the end of the tube in the waste water vessel.
7. Disconnect the 6mm tube from the inlet of EV2 (coming out of the NCG burette).
8. Place the 1 liter draw vessel filled with tap water on top of the Steam QM-3 so as to have good gravity flow.
9. Connect the 6mm tube from the 1 liter draw vessel filled with tap water to the inlet to EV2.
10. Position and level a calibrated balance (scale).
11. Record the dry weight of a 500ml container.
12. Turn on the power to the Steam QM-3.
13. Open the valve from the draw vessel (slowly) to establish a cycle rate of the EV2 valve of approximately 30 seconds.
One cycle is from opening to closure of valve, you should be able to hear this.. If the environment prohibits
hearing go to the control panel and press up and down arrows to access sensor menu and watch ∆P2 value. it will
climb from 0 to about 400 then when it opens it will drop back to 0.
14. After the proper flow rate is established, let it cycle one more time and remove the tube from the waste container
(be careful not to shake out any remaining water from the tube).
15. Place the tube in the 500ml container (from step 11).
16. Allow the EV2 valve to cycle exactly 20 times (keep track of the number of cycles).
17. After exactly 20 cycles remove the tube (be careful not to shake out any remaining water from the tube.
18. Record the mass of the water and container together to nearest tenth of a gram, and calculate using the following
formula:
(water + container) - the dry weight of container(step 11)
20 = average mass of water per cycle
19. On the Steam QM-3 display pad press left and right arrows simultaneously to access the code menu.
