In previous articles, we discussed the flow calculation method of the peristaltic pump. In this article, we will introduce how to set the flow rate of the Lead Fluid peristaltic pump.Generally speaking,there are three commonly used methods.
♦ 01 Query Speed-Flow Rate-Volume Correspondence Table
⌊ Suitable for Lead Fluid BTS series/WTS series/WGS series speed variable peristaltic pump⌉
According to the model of the head and tube, query the “tube flow reference table” dedicated to Lead Fluid, and directly obtain the speed corresponding to the flow rate.
Or search the amount of fluid transferred per revolution,according to the flow calculation formula, calculate the speed corresponding to the required flow, and then adjust the speed to obtain the corresponding flow.
This method can roughly set the speed and flow rate, easy operation, commonly used in ⌈speed variable peristaltic pump⌋

♦ 02 Calculate The Corresponding Relationship Between Speed and Flow
⌊ Suitable for Lead Fluid BTS series/WTS series/WGS series speed variable peristaltic pump⌉
Set an arbitrary speed n1, and measure the actual liquid quantity Q1 transmitted in a certain time t1.
Calculate the flow coefficient a according to a=Q1/n1, then calculate the speed n2 according to the formula n2 =Q2 / a, adjust the speed to get the required flow L1.
The flow rate accuracy obtained by this method is high, but the operation is complicated, and it is suitable for the ⌈speed variable peristaltic pump⌋ that requires high flow rate and quantitative accuracy.
When external working conditions change or run for a long time, flow calibrate must be performed in time to maintain high flow accuracy.
♥ External working conditions: mainly refers to the replacement of the pump head,the tubing, the change of suction and lift.

♦ 03 Direct Input Flow Parameters
⌈ Suitable for Lead Fluid intelligent flow peristaltic pump and intelligent dispensing peristaltic pump ⌋
Lead Fluid intelligent flow peristaltic pump and intelligent dispensing peristaltic pump use high-definition LCD touch screen display,just select the pump head and tube model, and then directly input the flow parameters.
The flow accuracy obtained by this method is high, and can be completed only according to the prompt,convenient operation, and high degree of intelligence.
When the working conditions change or run for a long time, it is necessary to perform flow calibrate in time to maintain a high flow accuracy.
The peristaltic pump and flow sensor form a closed-loop system, which can automatically calibrate the flow in real time and realize stable flow transmission for a long time.
