ZJ-LCD-M Digital Flow Meter Filling Controller LCD Display G1/4 G1/2 G1 Thread Dosing Machine for Industrial Liquid

1.NOTE

Water Pressure Required:System works only with water pressure between 0.5–8 kg/cm² (7–114 psi). It will not functionin zero-pressure environments.

Flow Meter Compatibility: Please confirm the pipe diameter before purchase. Different diameters require different K-factor settings on the controller for accurate measurement.

Calibration: K-factor is user-adjustable. You can fine-tune it to improve flow accuracy.

Default Language: The screen displays in English only.

Temperature Display: If you need temperature readings, a temperature probe must be purchased separately.

5.FAQs

Q1: Can I use this system without water pressure?
A1: No. A minimum pressure of 0.5 bar is required for proper flow measurement and valve operation.

Q2: How do I determine the K-value for my flow sensor?
A2: Refer to the sensor’s pulse frequency formula (e.g., F = 7.5 × Q), and set K accordingly in the controller.

Q3: Can I measure temperature as well?
A3: Yes, but a separate temperature probe is required (not included by default).
