Reliable level control for environmental applications SITRANS LU150/180
The SIEMENS SITRANS LU150 is a short-range general purpose, 2 wire, 4 to 20 mA loop powered transmitter ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 m (16.4 ft). The SITRANS LU180 is the intrinsically safe model.
Designed primarily for liquid applications in the environmental, water/wastewater, and energy management industries, the device is ideal for non-contact continuous level measurement of liquids and slurries in open or closed vessels.
The reliability of the level readings are based on Sonic Intelligence echo processing algorithms that Siemens has been refining for decades. These algorithms differentiate the true material level echoes from the false ones that can result from acoustic or electrical noises, as well as from agitator blades in motion. It's effective, accurate, unique, and it's exclusively Siemens.

Analytical measurement and control of pH within a system is necessary for many processes common applications include food processing, wastewater treatment, pulp & paper production, HVAC, power generation, and chemical industries.
To maintain the desired pH level in a solution a sensor is used to measure the pH value. If the pH is not at the desired set point, a reagent is applied to the solution. When a high alkaline level is detected in the solution, an acid is added to decrease the pH level. When a low alkaline level is detected in the solution a base is added to increase the pH level. In both cases the corrective ingredients are called reagents.
Accurately applying the correct amount of reagent to an acid or base solution can be challenging due to the logarithmic characteristics a pH reaction in a solution. Implementing a closed-loop control system maintains the pH level within a certain range and minimizes the degree to which the solution becomes acidic or alkaline.
An example of an automatic pH level control system is a water treatment process where lime softened water is maintained at a pH of 9 using carbon dioxide as a reagent. As the untreated water (or influent) enters the tank, the pH is continuously monitored by the pH sensor. The sensor is the feedback device to the controller where the setpoint is compared to the control value. If the values are not equal, the controller sends a signal to the control valve that applies carbon dioxide to the tank. The reagent is applied to the tank at varying rates to precisely control the pH level. With the pH level at 11 detected by the sensor, the controller commands the control valve to open and introduce more carbon dioxide. As the increased carbon dioxide mixes with the influent, the pH is lowered in a controlled manner. Reaching the setpoint, the carbon dioxide flow is minimized and the process is continually monitored for variation. The effluent is the treated water that is discharged out of the tank. The process continues to provide the lime softened water at the desired pH level.
Make sure your equipment is compatible with your process!
Here is a handy quick reference guide for corrosion and material compatibility that can be applied for process control equipment (thanks to QCI Valves).
This chart is a guide to the engineer in the selection of materials for corrosive services. No one material can be expected to handle the wide variety of corrosive media found in industry today. Therefore, the user must decide, based on experience, which properties are of prime importance in their application.
The process equipment in contact with the media should carry an A Rating. This chart is intended to be a guide, and if any questions exist on the application of a material, actual tests should be performed to determine the suitability of the material. When in doubt, ALWAYS consult an application expert.
No matter what industry you’re in, the price of your inputs is bound to
fluctuate – usually trending in a direction that doesn’t favor profits.
You can’t control the rising costs of raw materials and energy, but you
can control how much you get out of them. The simplest way to do this is
by maximizing the efficiency of your equipment.
Performance and productivity are directly related to energy use, reliability and maintenance costs. The improved performance offered by a highly efficient drive train helps increase output and decrease energy consumption. It also reduces wear and tear, thereby limiting maintenance costs and downtime while extending the life of your equipment. To attain this level of efficiency, one need only turn to the application-specific engineering found in integrated drive systems.

This video provides excellent information on installing magnetic flowmeters when you do not have optimal piping situations. The video also provides the viewer with an excellent overview of how Magmeters work.
The presentation reviews topics such as how Magmeter works, mounting configuration, best practices, alternatives for when required upstream/downstream piping distances are not available, the importance of a full pipe, and what kind of accuracy you can expect in less than ideal piping situations.
