FAQ

Where to installation circulate meter in chilled water?

In order to make sure the correct measurement of chilled water flow meter, the installation position and technique should be accurately selected

Requirements for straight pipe part: it must be put in horizontally on the pipe (the pipe tilt is less than 5). During set up, the flowmeter axis must be concentric with the pipe axis and circulate course should be constant. The length of the upstream pipe should be no much less than 2D straight pipe section. If the set up site permits, it is strongly recommended that the upstream straight pipe section be 20D and the downstream pipe section be 5D.
Requirements for piping: The inside diameter of the upstream and downstream piping of the set up level is the same as that of the flowmeter.
Requirements on by-pass pipe: In order to ensure that the upkeep of the flowmeter does not affect the normal use of the medium, the cut-off valve (cut-off valve) should be put in on the entrance and rear pipes of the turbine flowmeter, and the by-pass pipe must be set at the identical time. Flow control valve to be installed within the downstream of the move meter, the upstream installed cut-off valve must be fully open when in use, to avoid the upstream part of the fluid produced unstable circulate phenomenon.
The requirements of the exterior setting: it is best to install within the indoor, should be installed within the out of doors, should use sunscreen, rain. Lightning protection measures, in order not to have an result on service life.
Requirements for impurities within the medium: In order to ensure the service lifetime of the flowmeter, the filter must be put in in front of the straight pipe part of the flowmeter.
Installation site: The flowmeter should be put in in a place that is straightforward to take care of and free from sturdy electromagnetic interference and thermal radiation.
What are the constraints of electromagnetic flowmeter at low temperature?

The low-temperature resistance of the info.
The electrical insulation of the electromagnetic flowmeter transmitter.
Can ultrasonic move meters measure chilled water flow?

Ultrasonic flowmeter can measure the move fee. The temperature shouldn’t exceed -40℃~160℃. Requires a complete test tube and uniform medium. It can display instantaneous circulate rate, move fee, cumulative flow price and cumulative operating time.
Ultrasonic calorimeter can measure warmth supply, flow price and temperature monitoring. Air conditioning heating and cooling capability measurement.
How to measure the chilled water flow rate of a chiller??

The following is our experience sharing: chiller chilled water circulate measurement approach. We hope will most likely be helpful to you.
1. Chiller into and out of the water strain detection of water pipes

By detecting the return water strain and outlet water stress values. Check the water flow rate of the chiller under the inlet and outlet water pressure distinction in the random handbook of the chiller.
Refer to the corresponding unit water circulate price table or chart in the handbook. Thus, decide whether or not the refrigeration system is normal or not.
And by this distinction to determine which part of the transmission pipe resistance value is larger. And develop the corresponding rectification plan and action.
2. Test the refrigerator return water temperature and water temperature (the unit must be in normal condition)

After half-hour of energy on, verify the system or chilled water system inlet and outlet thermometer via the unit control system parameters.
The inlet water temperature and outlet water temperature may be read when the unit is running. The difference should be about 4-6 levels.
If the distinction between the inlet and outlet water temperatures is simply too large, the water system is flowing too little water through the plates. This could cause the gear to fail to function properly or be broken.
3. Pump operating current detection

By detecting the running present of the fridge water pump, and the rated current for comparability. You can decide whether the actual water circulate is greater than or lower than the rated water circulate of the pump.
Combined with the earlier parameters complete judgment. In order to get an correct chiller system test and analysis report.
four. Compressor copper tube suction temperature detection (only when the refrigeration operation)

If the fridge and freezer is turned on after half-hour

The compressor suction temperature is detected to be decrease than 0 degrees. It means that the water flow in the water side heat exchanger isn’t sufficient, which causes the evaporation temperature and evaporation stress to drop.
and causes Freon to nonetheless evaporate and take up warmth from the suction tube flowing from the evaporator to the compressor. It will lead to the compressor suction temperature beneath 0 levels.
In addition, it is necessary to eliminate the drop of evaporating stress and evaporating temperature caused by low water temperature setting worth.
Non-standard low water temperature unit could be considered regular as long as the compressor suction superheat diploma is 6-8 degrees Celsius.
So underneath the traditional water circulate. The compressor suction temperature is mostly higher than 0℃. Below this value, the water system problem must be excluded.

How to measure the chilled water circulate rate of a chiller??

The following is our expertise sharing: chiller chilled water move measurement technique. We hope it will be useful to you.
1. Chiller into and out of the water strain detection of water pipes

By detecting the return water strain and outlet water strain values. Check the water move rate of the chiller underneath the inlet and outlet water pressure difference within the random manual of the chiller.
Refer to the corresponding unit water circulate price table or chart in the manual. Thus, determine whether or not the refrigeration system is normal or not.
And by this distinction to discover out which section of the transmission pipe resistance value is greater. And develop the corresponding rectification plan and motion.
2. Test the fridge return water temperature and water temperature (the unit must be in normal condition)

After half-hour of power on, examine the system or chilled water system inlet and outlet thermometer by way of the unit management system parameters.
The inlet water temperature and outlet water temperature can be learn when the unit is operating. The difference should be about 4-6 levels.
If the difference between the inlet and outlet water temperatures is simply too massive, the water system is flowing too little water via the plates. This might cause the tools to fail to operate correctly or be damaged.
3. Pump running present detection

By detecting the running present of the refrigerator water pump, and the rated present for comparability. You can determine whether or not the actual water flow is greater than or lower than the rated water flow of the pump.
Combined with the earlier parameters complete judgment. In order to get an accurate chiller system test and analysis report.
4. Compressor copper tube suction temperature detection (only when the refrigeration operation)

If the fridge and freezer is turned on after half-hour

The compressor suction temperature is detected to be lower than 0 levels. It signifies that the water move within the water facet warmth exchanger isn’t enough, which causes the evaporation temperature and evaporation strain to drop.
and causes Freon to nonetheless evaporate and take up warmth from the suction tube flowing from the evaporator to the compressor. It will lead to the compressor suction temperature under 0 levels.
In addition, it’s essential to get rid of the drop of evaporating strain and evaporating temperature caused by low water temperature setting value.
Non-standard low water temperature unit can be considered regular so lengthy as the compressor suction superheat degree is 6-8 degrees Celsius.
So beneath the conventional water flow. The compressor suction temperature is mostly greater than 0℃. Below this value, the water system downside needs to be excluded.
