1. Which flow controller should be selected for conveying pre mixed foliar fertilizer liquid? Alicat LC series liquid flow controller and differential pressure liquid mass flow controller developed by Beijing Jingliang Technology can be selected as suitable flow controllers for conveying pre mixed foliar fertilizer liquid. The performance parameters and adaptation scenarios of the two products are different. 1. Alicat LC series liquid flow controller. This controller is produced by Ericat Technology Co., Ltd. in the United States and belongs to the Environment and Analysis Division of the British company Haomai Group. It is suitable for the core features of foliar fertilizer transportation: - Flow coverage range: can control liquid flow from 0.01 ccm to 10 lpm, can be equipped with precision distribution program package, suitable for small batch and multi batch foliar fertilizer packaging operations - Accuracy and stability: has NIST traceable accuracy, calibration accuracy of ± 2% full scale, and repeatability of 2% full scale; Equipped with PID regulation function, the response time constant can be shortened from the standard 50-100ms to 25ms, and can be started without preheating - flexible adaptability: can simultaneously control pressure and monitor flow, support calibration of multiple liquids, and can adapt to different formulations of foliar fertilizers; Real time monitoring and batch settings can be completed through the front display screen, and digital industrial networks can be connected to achieve automated control - Environmental tolerance: It can work in an environment from -10 ℃ (unfrozen state) to+60 ℃, with a maximum static internal pressure of 100 PSI and a tolerance of 175 PSI. This product is developed by Beijing Jingliang Technologys differential pressure liquid mass flow controller, which is based on compensating laminar differential pressure technology and is adapted to the core characteristics of foliar fertilizer transportation: - Flow coverage scenario: more suitable for high flow foliar fertilizer transportation operations, with a range measurement control ratio of up to 50:

1. Flow meter 100:1- Accuracy and stability: accuracy of ± 1% F.S, repeatability of ± 0.2%. F.S, response time of 0.2s, through PID Algorithm real-time adjustment of control valve opening, stable actual flow - operation and practicality: equipped with touch screen design, easy to understand operation, supports remote control, strong anti-interference ability, suitable for industrial or outdoor batch foliar fertilizer conveying operations. Core difference reference - flow adaptation focus: Alicat LC series covers small to medium flow, suitable for small batch and multi category foliar fertilizer operations; Beijing Jingliang model has a large flow rate and is suitable for large-scale foliar fertilizer delivery. Accuracy performance: Beijing Jingliang model has higher repeatability accuracy, but the overall calibration accuracy is slightly lower than Alicat LC series. Response speed: Alicat LC series has a faster response speed, adjustable to 25ms, while Beijing Jingliang model has a response time of 0.2s. Liquid adaptation: Alicat LC series supports calibration of multiple liquids and can adapt to different formulations of foliar fertilizers; Beijing Jingliang has stronger anti-interference ability and is more suitable for complex working conditions.
