Foxboro’s magnetic flow meter
Water flow measurement.
Foxboro’s magnetic flow meter is designed for all types of flow measurements that can be encountered in the municipal sector. It is recognized for a long time as a reliable and solid instrument. All diameters are available for applications of flow measurement of drinking water or wastewater.
For wastewater flow that is found in manholes, Drexelbrook’s ultrasonic is used. This equipment contains in it’s memory all calculations of the types of channels used in the municipal sector such as Parshall flume, V-Notch, Weir, etc. This unit is inexpensive and highly resistant to low temperatures.
Thermo measurement systems
Water flow measurement with portable units.
To check the flow of water pipes, Thermo has portable measurement systems. For drinking water or clean water, Thermo’s “Transit Time” system is used. For dirty water or with particles in suspension, Thermo’s “Doppler” system is used. These systems are very efficient and are used to control leakage.
Foxboro’s conductivity and pH probes
pH and conductivity measurement of water.
In the municipal sector, chlorine is added to kill bacteria. The dosing monitoring is done using Foxboro’s conductivity and pH probes. This controls the dosing of chlorine and reduces the cost of this product.
Level measurement in artesian wells.
Drexelbrook offers a continuous probe to measure the water level of wells. This measurement is very difficult because there is virtually no space for the probe. The Drexelbrook probe is installed directly on the pump conduit. It is used to give the actual level of the water and avoids burning the pump if the water level is too low.
wireless communication between pumping stations.
Communication between pumping stations is critical. Elpro radios help send the information to various pumping plants and thus help to improve the data processing of information to the control panel. A radio may be used as a repeater from a pumping station to pick up the signal of a well that is very far.
Buffer tank level.
In the water network system, there is a tank that’s there to balance the excessive pressures (water hammer). Drexelbrook offers a level measuring probe for that tank which is very robust and accepts the clogging produced by the wastewater. This system is very reliable and does not require maintenance.
Submersible pump vibration measurement.
There exists a protection for submersible pumps to prevent failures or blockages. Wilcoxon’s probe is installed underwater permanently to protect this type of pump. It allows to predict in advance the corrections to be made to the pump.
Drexelbrook’s sonar system or Markland’s optical system
Sludge level measurement.
In wastewater treatment plants, there is a settling sludge tank. To read the sludge level in the tank which is filled with water, Drexelbrook’s sonar system or Markland’s optical system are used. However, Drexelbrook’s sonar system can read the level of sludge and the interface with two separate output signals. This allows, in heavy rainfall, to not lose the veil of sludge and return sediments back to the environment.
Oxygen percentage in water.
In wastewater treatment plants, it is important to know the percentage of oxygen of water before returning it to the environment. Foxboro has a system that measures the oxygen level of the water with a very high efficiency.
