Process Instruments used in Poultry Industry

Below is a reference application which process instruments used in Poultry Industry. Let’s see the case how we choose instruments to measure liquid flow, gas flow, also temperature and pressure information.

Case:
We are interested to know more about the instruments that your company offers. Specifically, we need magnetic flow meter to measure substrate from biogas plants, Thermal mass flow meter to measure biogas flow rate, and temperature and pressure transmitter to measure from the internal part of the digester. The medium is substrate from laying hens guano at 10% of dry matter. The operational temperature is 38-40°C. Also, we need more of this temperature transmitter but to measure inside a 75 mm PPR pipe. In this case, the medium is water and the temperature range is for 30-90°C.

Magnetic flow meter
Here is the information that you need:

1.       Magnetic flow meter: (with display)
a.       Substrate: laying hen guano liquated at 10% of dry matter. This should be corrosive.
b.       Electrode material: 316 SS
c.       Mag meter Flow meter size: DN150
d.       Flow range: the average flow of substrate is 16,1 m3/h
e.       Operation temperature: 38 -40 °C
f.       Mag sensor Operation pressure: 1-3 bar

2.       Biogas flow meter: (with display)
a.       Average flow: 615 m3/h
b.       Biogas composition: 65% CH4, 35% CO2
c.       Pipe size: 148 mm internal diameter.
d.       Operation temperature: 38°C
e.       Operation pressure: 100-120mbar

3.       Pressure transmitter: (without display)
a.       Connection: ½’’ NPT
b.       Pressure Range: 0 – 650 cm H2O
c.       Operation temperature: 38°C

4.       Temperature transmitter: (without display)
The temperature transmitter will be mounted in a plastic tube-PPR; PPR is a plastic tube special for hot liquid transportation. At the tube it is installed a screwed connection and then, the sensor is screw up upon this connection. That way, the sensor is placed at the center of the pipe diameter. Below is an example of a screwed PPR connection.

Temperature transmitter

a.       Connection: ½’’ NPT
b.       Sensor length: as long as possible (here we have an offer for 1200mm)
