At present, the heat metering market commonly used heat table is divided into mechanical heat meter(mechanical energy meter) and ultrasonic heat meter(ultrasonic energy meter).Heat energy meter is suitable for measuring
the heat exchange, known as the heat transfer fluid or liquid absorbing thermal
energy conversion equipment, which consists of a flow sensor, temperature
sensor and heat calculator three parts. Heat energy meter (thermal meter), also
known as Heat Meters, heat energy calculator, both measure heating system for
heat and also measure heat absorption cooling system.
Heat energy meter (heat meter) is used to
measure and display the water flow through the heat exchange system release or
absorb heat. Heat energy meter, is also known as energy meters. The heat energy
meters are installed at the inlet pipe or outlet pipe to measure accurate
metering and intelligent control of charges of the heat consumption. Its working
principle is to install Heat Energy Meters in the heat exchange system, when
water flows through the system, according to the supply and return water flow
temperature, from the data from the flow sensors and temperature sensor as well
as the water flow time, the heat energy meter will calculate the released and
absorbed energy through the calculator.

This situation of growing cucumbers in house is very likely to be caused by the disease. The disease begins to produce oval or spindle-shaped, white lesions on the vines, overflowing with amber resin colloidal liquid, stem shrinkage in later stages. The longitudinal fissures are messy, sometimes with many black spots. When the disease is severe, the stem segments become dark, rotten and broken. The specific prevention and control method is as follows: spraying 50% Trimone suspension 3000 times liquid or 60% Baitai water dispersible granule 2000 times or 25% Kai Run EC 3000 times or 50% protective power wettable powder 500 times Liquid or 10% Difenoconazole Dispersible Granules 2000 times, etc. are respectively mixed with "Tianda 2116" 600 times liquid + Tianda organic silicon 2000 times spray, 7~10 days, continuous spraying 2~3 Times. Rainy days can be used 30% chlorothalonil smoke agent 250 grams per acre smoke, spray 7 to 10 days once, continuous control 2 to 3 times.
