Reduced Downtime in Brewing with Pre-calibrated pH Memosens Sensors Designed for Longer Sensor Life

pH is monitored at the filler in each packaging line, right before the product is bottled or canned. Downtime is unacceptable and costly.


Being the final quality assurance measurement, high precision is required. Any drift, delayed response, or inaccuracy must be immediately addressed through calibration or sensor replacement. 


Typical  contributors to unreliable sensor performance are:

Reduced Maintenance and Downtime in Corn Mash Tanks using
an Automatic Cleaning System and Pre-calibrated pH Sensors

The slurry of a corn mash tank contains liquids and fine solids particles. The thick slurry can quickly plug the junction/diaphragm of a pH sensor causing it to drift. This often requires frequent maintenance to clean the junction and recalibrate the sensor. In some cases the sensor is just replaced with a new one. Removing a pH sensor by hand from the process can be dangerous due to high temperatures and pressures.... Continue reading

The value of enhanced sensor diagnostics


Remember when it was the screech under the hood or the burning oil smell that told you something was wrong with your car? What did we do before our cars told us it was time for service? We didn’t just get rid of our car and buy a new one, we brought it to the mechanic for evaluation and repair.  


Today, we have clear diagnostics on our car’s dashboard that pinpoint the problem and indicate when it’s time for service. The same benefit is available with Memosens smart pH sensor te... Continue reading

Wet Gas Scrubbers pH Control

October 18, 2017
Category: Application Success Story
Environmental Safety through Critical pH Control 

Wet gas scrubber systems, also known as chemical scrubbers or gas scrubbers, are a type of air pollution control system that removes particles and hazardous gases from industrial exhaust streams.    


The scrubber uses caustic liquids and injects them into the ventilation stack. This traps particulates and neutralizes the acid in the gas stream which then falls down to the bottom of the stack. The liquid that is collected is then sent to the wastewater treatment pla... Continue reading

Better Chemical Dosing Control Extends  Filtration Membrane Life

Reverse Osmosis (RO) is a purification process which removes Total Dissolved Solids (TDS) in water by applying pressure to feedwater, forcing it through a semi-permeable membrane and allowing pure water to diffuse.


Conductivity is an important measurement for RO. Having the ability to measure a very low conductivity accurately is critical. Using a conductivity electrode is a common way to test RO water quality and membrane performance. Ultra pure water is... Continue reading

How accurate is my pH sensor?

August 25, 2017
Category: Memosens

You should be asking, how accurate is my calibration procedure?


When there is an issue with pH measurement accuracy the blame is typically laid squarely on the sensor. However, calibration procedure and execution can be equally to blame. Below you will find some helpful hints that will assure you produce a repeatable, accurate calibration.

 

Before we dig in, let’s look at some of the key components to a successful calibration procedure:

Fast and Reliable Detection with Memosens Conductivity

Heat exchangers are used throughout many industrial plants to cool and convert steam into condensate. Once the steam has turned to condensate, it’s purity is high and conductivity value is low. Condensate contamination is very costly and affects efficient operation of the plant, or even worse, the contamination can cause environmental pollution. Monitoring the conductivity of the condensate leaving the heat exchanger is a reliable method to ensure the heat exchanger is functioning pro... Continue reading

It’s 3:00 AM and I’m Out Calibrating a pH Sensor

Category: Memosens

Author: Shawn Little


Whether you are on 1st, 2nd, or 3rd shift, calibrating sensors seems to always happen at the worst time. It’s pouring down rain, snowing, +100º heat at noon, or below freezing in the middle of the night. I’d rather be in a climate controlled shop doing calibrations at a time I planned. Wouldn’t you?  To me that’s a no-brainer!


In fact there are three no-brainers to me when it comes to pH calibrations:

Improving Efficiency with Reliable Conductivity Measurements — CIP Cleaning Agent Control and Rinse Water Purity Monitoring

Conductivity measurements are used to control the CIP process as well as monitor the purity of the water used during rinsing cycles. Unreliable measurements can cause downtime or even worse, contaminated batches due to leftover product or detergents.

It’s Probably the Cable!

May 31, 2017
Category: Memosens

In the pH business, most measurement performance issues are blamed on the sensor. The sensor is the primary measurement element of the loop and is directly exposed to the process. Therefore, it must be the source of the problem, right?


In my experience, most pH problems are typically caused by something more rudimentary. It is these two factors that are oftentimes overlooked – sensor connections and cables.


In this post, I’ll be focusing on the cable. Continue reading

Confidently Meeting Environmental Compliance Requirements — Wastewater pH, ORP, and dissolved oxygen monitoring

Depending on the feed entering the wastewater facility there can be a wide range of pH. Very low pH liquids can damage parts of the treatment system and potentially kill the good bacteria in the clarifier. Knowing in advance that low pH liquid is entering the process allows the operators to divert influent to protect the system. Because the SE 555 pH electrode is designed for dif... Continue reading

Antiquated  Analog Technology vs. M4 Knick Digital Loop — Utilizing a Solar-Powered Engineer Solution

With traditional analog pH/ORP technology there are a number of challenges customers face.

An analog connection to the sensor is typically not submersible. M4 Knick’s digital Memosens® sensor connections are inductive. This is unlike all other digital and analog systems which use a conductive non-submersible connection. To get around this manufacturers will “pot” the cable into the sensor which forces the customer to completel... Continue reading

Powerful Compact Analyzer Boosts Performance while Reducing Costs

April 12, 2017
Category: Memosens

It has long been common practice when making pH/ORP, conductivity, and oxygen measurements that a fixed analyzer be mounted near the sensor.  The analyzer serves several purposes.  It is the display, the calibration tool, and the source of the output signals for data collection.


Analyzers represent a significant portion of the loop cost when making these measurements.  The cost shows up as the following pain points:

Water Quality Monitoring to Optimize Boiler Performance — Using pH, DO, and Conductivity

An important component of steam boilers are the tubes. The pH of the boiler water is normally kept alkaline to facilitate the formation of a thin oxide layer on the tubes. This oxide layer acts as a protective barrier against corrosion. Sodium phosphate & sodium hydroxide are used to promote this oxide formation, but too much of these chemicals can cause problems. Accurate pH monitoring can help prevent these issues. M4 Knick’s SE 558 pH electrode... Continue reading

How Can a Toothbrush Make Your pH Measurement More Reliable

Category: Memosens

Author: Shawn Little


OK, OK, a toothbrush isn’t part of pH measurement (unless you’re using one to clean your sensors…not recommended!). However, inductive charging technology introduced by Braun's Oral-B electric toothbrush was a precursor to ground breaking improvements in in-line pH/ORP, oxygen, and conductivity sensors.  


If you’re not using inductive technology for dental hygiene, it’s possible you’re using it for other portable device charging. This charging method has now become a... Continue reading

I’ve been on the road for the last four years talking about almost nothing but pH (my wife and kids would find that extremely boring…if they actually knew what I did for a living).  During my time in planes, trains, automobiles, and in chemical plants, refineries, power plants, and what have you, I’ve learned something real. Making pH measurements is so painful that it no longer hurts.  You know what I mean? It’s like that ache from an old injury, or just old age, that you know is there b... Continue reading
