Arduino water flow control

I want to create a Arduino based solution to provide a controlled amount of heat removal from a experiment using a water cooling system.

As water flows through the heat block at about 5 litres per minute, it will warm up by approx 40 degrees C. We want to measure the flow rate and the temperature of the water entering and exiting the block.
[Flow rate] x [temperature change] = [heat flow]

We will use this result to control the flow from a pump. If not enough heat is being removed, we will increase the speed of the pump, and vice versa.

It will require the following..
– Measure the temperature of 2 temperature sensors from DFRobot, model DFR0198
– Measure the flow of water, using Adafruit 5066 water flow sensor
– Control the flow rate of a submersible water pump (we’re still looking for a pump where we can control the flow rate from the Arduino)

The Arduino should be running software, controllable via a serial connection to a Windows PC.
The PC will send a integer over the serial connection for the Heat to be removed.
Every second, the Arduino will send the Temperature of each sensor, and the flow rate.
