Liquid Weighing Dispensing Filling Machine, w/ Diaphragm Pump 

The AWM-L01 liquid weighing dispensing machine, or gravimetric liquid dispenser, is a closed loop dispensing/packaging system by weight. It provides a higher level of accuracy than the timer controlled precision dispensing system. The timer controlled dispensing system is an open-loop controlled system with no feedback. A timer is the only factor which controls the amount of dispensed liquid in a time controlled dispensing system, while many other factors can also affect its dispensing accuracy, reliability and repeatability.

For example, some liquid may change its viscosity with temperature, pressure, time or size of the molecule (from batch to batch). If the ambient temperature changes, or the molecule size varies, the amount of dispensed liquid will change as well. In addition, liquid level in the reservoir, solid particles in the liquid, the aging of the pump and the condition of dispensing tubing can all affect the amount of dispensed liquid in this timer controlled open-loop system. User has to weigh the dispensed liquid manually to control the final quality.

This AWM-L01 liquid weighing machine can solve all the problems presented in only using a timer controlled dispensing system. The dispensing process can only be stopped when the set weight is reached. Normally, a 3% accuracy can be achieved without any tuning. 1% or less accuracy can be reached easily after fine tuning. 

Key features are below:

1). Universal design for different dispensing projects. For traditional dispensing systems by time, user may need to adjust the dispensing time for different types of liquid or different liquid pressure. Dispensing by weight can eliminate all these time related factors for better accuracy and user-friendly. 

2). Automatic dispensing mode for easy use. Exclusive automatic mode can sense the placement of new container, auto-tare the weight of the container and auto-dispense by your set weight. It will auto-zero when you remove the container from the scale. Users don’t need to press any keys during the whole process.

3). Memory feature. User can store up to 4 pre-set dispensing set values in the machine for future use.

4). This machine has one built-in diaphragm pump.

5). Compatible liquid: pure liquid, free of impurities, non-viscous, non-corrosive, like vinegar or perfume. Oil is not compatible. 

Note 1: Please see our AWM series product list here. Please contact us for your special needs. 

Note 2: The built-in pump & tubing has limited life time. It could be a little bit difficult to service and repair this whole machine. For mass production customers, please consider dispensing machine AWM-L02 with external peristaltic pump. External pump will be easier to be serviced/repaired.
