Are you having issues with your ultrasonic level transmitter but can’t decide the best route to solving your problem? Whether it concerns the installation, maintenance, or reporting process, why not speak to an expert and find out what your options are? My colleagues and I have discussed this subject in great depth over the years, […]

When you’re working in the water and waste water industry, the last thing that you want is for your water treatment plant to have performance issues like build-up, inaccurate measurement readings and compliance issues. Your primary focus is to meet environmental regulations and to ensure that your plant is operating as efficiently as possible. But, say that your plant does endure problems, what then?

Have you ever bought something and put it together, or installed it, and it just would not work?

In ultrasonic level instrumentation , a controller measures the time-of-flight of the sound wave produced by an ultrasonic transducer for the round trip between the transducer and the target (material level). The speed of sound is the distance travelled per unit time by a sound wave. In dry air at 68°F, the speed of sound is 1,129 ft/s.

In the first part of this blog, I talked about closed pipe flow and the benefits and disadvantages it can have. In part two, I’d like to focus on open channel flow and how this option can be used to measure water and wastewater flow. Measuring flow through an open channel is a popular choice for water/wastewater applications. It’s easy to see why, with ease of installation and maintenance over time. In open channel flow, the use of a primary measurement device, such as a weir or flume, along with a non-contacting level measurement device is used to determine the flow. There are several choices for the primary measurement device as well as the level device. Let’s take a look at just a few of the choices for this type of flow. The Primary Measurement Device (PMD) is a key component of open channel flow measurement. A great deal of thought should be put into the selection of the primary measurement device. The flow rate that you have today may not be the flow rate that you will have tomorrow and must be considered to avoid the purchase of an inadequate system. Other items to consider are the accuracy of the PMD, maintenance and the fluid to be monitored. Installation of the PMD is critical for the proper reading of the open channel flow meter selected to measure the head of the flow. Improper installation or sizing of the PMD will impact the overall performance of the system.

I think that in this day and age, everyone knows a variety of ways to conserve at least a little bit of energy and save money while doing so. This is true at home, and across any industry. Take for instance the energy consumption across the United States just in the water treatment process. With thousands of water public utilities across the nation, the amount of energy usage is significant enough to make the statistical charts.
