Measurement procedure |
| Simplest experiment with tap water.
- Switch on PC, and power supply of transducers.
Start program OHMICAS (time step 1 s, 9 channels).
- Set 3-way cock K1 to position 1 (K1/1), and open valve V2 (filling water).
Check water level visually (glass gauge) and on display (channel 8).
After filling close V2.
- Set cock K3/1 and K1/4. Water flows to the outlet.
Estimate the flowrate using F10. Adjust the flowrate by valve V1.
- Switch on heating and adjust electrical power (check overloading on control panel).
Wait until the steady state is achieved.
- Precise value of flowrate can be obtained by measurement of volume at a time.
Use stop-watch and calibrated vessel (2 to 8 liters).
