If we're running two pumps, why aren't we getting twice as much flow? v.17Brian Gongol
A single pump operating at a time is easy to figure out. Adding a second pump (or more) makes things a bit more complicated. That complication can deliver a whole lot of additional flow -- or it can become an exercise in futility.

Lately, there has been an increasing fascination with employing genetic algorithms (GAs) to tackle
intricate optimization issues. Genetic algorithms (GAs) draw inspiration from natural selection and have
demonstrated efficacy in discovering optimal solutions for many problems, such as diet optimization. This
research presents a genetic algorithm (GA) approach to estimate individuals' optimal daily calorie
intake. The proposed approach considers the individual's age, gender, height, weight, exercise level, and
dietary limitations. In addition, it considers the nutritional composition of various dietary items. The
strategy aims to create a daily meal plan that fulfils the individual's calorie requirements and supplies all
necessary nutrients. The suggested technique was assessed using a dataset consisting of 100 people. The
findings demonstrated that the approach successfully produced dietary regimens that satisfied the
individual's specific caloric requirements and encompassed all vital elements. The technique also
produced diverse and captivating food menus. Additionally, we recommend a fitness function that
assesses each suggestion's appropriateness for a given user. Ultimately, to completely comprehend the
characteristics and functionality of our system, we conducted experimental re

Applications
The VARIPULSE® controller uses digital and analogue signals to
provide proportional control of the flow rate of Series GTM
A and
Series GTM
M metering pumps. The controller is recommended for
use in many applications, including water and wastewater treatment,
surface treatment, irrigation, physical and chemical treatment and any
applications where automated, proportional pumping is required.
Adjusts and controls the flow of Series GTM
A and Series GTM
M pumps.
Two versions are available:
Frequency variation
Three operating modes: manual, proportional by 4-20 mA analog
signal and proportional by pulse
Principle
Vector voltage control electronics compensate for variations in power
supply voltage by generating and adjusting voltage and frequency to
control a three-phase motor either by frequency variation or through
a series of starts without compromising performance over the entire
operating range. The electronic delivers extremely accurate metering.

•4 mA: 0% of pump flow rate
•20 mA: 100% of pump flow rate
Flow rate controlled by voltage free contact or open collector
•Selection of flow meter
•Fittings flow rate (pulses generator meter): 1.5, 2.5, 3.5, 5, 10,
15, 25, 40, 60 or 100 m3
/h
•Reference volume: 0.25, 0.5, 1 or 10 l/pulse
•The VARIPULSE® calculates the coefficient to be applied in order
to optimize the pump speed according to its model
Example:
Fittings flow rate: 1.5 m3
/h
Reference volume: 0.25 l/pulse
Pump model: GM 50 with a stroke speed of 144 spm ie 8640 strokes/h
So, for fittings rated capacity, the pump number of strokes is 6000
strokes/h
Then the VARIPULSE® calculates the coefficient of optimization to
have a pump flow rate of 100% with the 6000 pulses stemming from
the meter which allows an optimal sizing of the pump.
The following graphs illustrate this example
•Selection of pump model
•Programmable flow rate from 1 to 100%
•Automatic modification of working mode to optimize the pump
