Sealand is a trustworthy manufacturer of CNG Dispenser Mass Flow Meter, LNG Dispenser Mass Flow Meter, LPG Dispenser Mass Flow Meter, ATEX, CE & IECEx approved.
With its high accuracy, wide rangeability and reliable performance, Sealand meter has been applied in many kinds of industries during the last 8 years. Unlike others who only focus on the measurement of liquid at normal pressure & temperature, Sealand has conquered the difficulty in the measurement under severe conditions, such as high pressure, high viscosity, high & low temperature.

2, mixed medication. The combination of two agents with different modes of action and mechanism can also reduce the occurrence of drug resistance. The single-point pesticide is mixed with traditional pesticides with multiple points, and the effect is better.
3. Adopt comprehensive prevention and control method. Organically combine measures such as chemical control, artificial control, and quarantine.
4, intermittent medication. If a pesticide has been found to be highly resistant, it should be discontinued or discontinued.
5. Adopt the correct application technique. It is essential that the effective dose and deposition distribution of the drug in the field are uniform. Appropriate application techniques should be applied to different vegetables and different pests, and the dosage and frequency of administration should not be easily increased. In addition, pay attention to the use of time, try not to take medicine on cloudy days.

Take CNG (compressed natural gas) for example. As the saying goes, the meter can measure anything else if it can measure CNG. It is quite hard to measure gas under high pressure. The sensor must be able to bear high pressure; in this way, the thickness of flow tube must be increased, so the transmitter shall be more sensitive to detect the signal; however, Sealand made it. Sealand's first model is specially designed for CNG dispenser, and now thousands of this model are put into use on the market.
How to prevent pests and diseases from developing resistance
1. Rotation medication. A single variety of pesticides can induce drug resistance, varieties with different rotation mechanisms, and rotation of biological pesticides, antibiotics and pesticides can produce good results.
