A: Calcium and magnesium are used as medium and trace element fertilizers. The general application methods are as follows.
   Soil application method: Calcium and magnesium micro-fertilizer can be used as base fertilizer, seed fertilizer or top dressing. Because of its long fertilizer effect, it can be applied every other year, usually by strip application or acupoint application method.
   Seed dressing: Dissolve with a small amount of water and spray on the seeds.
   Soaking seeds: soaking seeds and germination before planting, the time is 12 to 24 hours.
   Roots: When transplanting crops, calcium and magnesium micro-fertilizers can be applied by root-feeding method.
Spraying outside the root: Spraying calcium and magnesium micro-fertilizer outside the root is the most economical and effective method of application. It is better to wet the solution on both sides of the leaf.

Chemical Industry Mass Flow Meter
Sealand is a professional supplier of Chemical Mass Flow Meter, Chemical Mass Flowmeter, Chemical Flowmeter, Chemical Flow Meter, Chemical Coriolis Meter, ATEX, IECEx & CE approved.
The meter can work with a pulse receiver(Count). The connection is as follows. The resistance value is up to the cable length & the max. input pulse frequency of receiver. Current 10mA is suitable for most receivers; however, you can reduce the resistance value when the cable is long. The max. current could be 50mA. Please use the fixed frequency output function to check if the cable length & resistance value is suitable.
Please check following items before operation, and operate according to relevant rules.
a) If the meter is damaged during shipment and installation;
b) If the voltage is same as marked on nameplate;
c) If the fuse is correct;
d) If the meter is grounded properly.
e) If the Meter SN on the nameplate of sensor and transmitter are the same.
If everything is fine, please open all valves, make the pipeline full of liquid and then power on
the meter for warm-up for 20min before operation. Finally, conduct zero calibration after first
start, and shall do it again if the meter is moved to another site.
Preparation for zero calibration:
a) Power on the meter for approximately 20min for warm-up;
b) Run the process fluid through the sensor until the sensor temperature reaches the normal
process operating temperature.
c) Close the shutoff valve downstream from the sensor.
d) Ensure that the sensor is filled with fluid and the process flow has completely stopped.
