TQ-821 Ammonia Concentration Meter
TQ-821 Ammonia Concentration Meter
Product details
product overview：
The TQ-821 ammonia concentration meter is a new product developed by Beijing Shitong Sci Tech Innovation Technology Co., Ltd. based on the principle of vibration, introducing advanced production technology from the United States. The product design adopts plug-in installation, which is widely used for ammonia concentration detection in pipelines, open tank containers, and closed tank containers. It is well applied in ammonia preparation, ammonia incoming material detection, ammonia recovery and other processes.
The concentration of ammonia water directly depends on the vibration frequency received by the sensor inserted into the ammonia water. The sensor is equipped with a built-in temperature sensor to provide temperature compensation.
Product features:
● Plug in design, plug and play
● Continuous online measurement
● No moving parts, maintenance free
● Anti corrosion design can be tailored to specific working conditions
● Integrated temperature compensation
● Passed explosion-proof certification (Exd II CT4)
Can be designed as a long pole (length ≤ 4m)
Allow for the presence of small amounts of solids or bubbles
Not sensitive to environmental vibrations
● Direct insertion short rod type suitable for high-pressure pipelines (pressure ≤ 20Mpa)
