How To

Having trouble with the signal from your sensor? Maybe it only works occasionally, maybe there’s too much noise to establish a strong connection, or maybe you just don’t know what is wrong. One easy way to figure out what’s wrong is using a multimeter to test your sensor. Don’t worry, we will walk you through how to use a multimeter to troubleshoot your sensor and get it working properly in no time!

But wait - what is a multimeter and how does it work? Let’s take a quick look. After all, we’ve got a sensor to troubleshoot.

At the beginning of this year we introduced to you the Tank Cloud MND (short for Modbus Network Display). To review, this display unit connects to a Modbus network to provide local tank level readings. You can program it as a sniffer – displaying readings by “eavesdropping on the conversation” between the client units and the server – or you can use it as the server and poll the clients sensors on the Tank Cloud network.

Today we would like to tell you a little more about the MND as a server.

If you use the DCR controller, such as the 1003/4 or the 1005/6, you may find yourself looking at blinking lights for relays that aren’t being used. It does NOT mean that something is wrong; it simply means that some default settings need to be changed to deactivate the unused relay.

Keep in mind that the controller is functioning properly, and will continue to do so even if unused relays are not deactivated.

Another video on programming the LPU-2428, this one covers setting the sensor up for volume measurements. The video is quick and shows how easy it is to program the sensor.

This video shows how to access and set the units of measure for the PG7 digital pressure gauge. The ability to select units of measure eliminates the need for multipliers, and allows operators to understand pressure in any engineering unit needed.

All programming is done through the sensor's built-in keypad and display. Programming is quick and easy, which makes implementation a very short and painless process.

Our digital pressure gauges can be set up using the "Custom Units of Measure" function to read in pounds. To do this, you need to figure out the multiplier for converting psi to pounds based on area where the force is applied. The manufacturer of the ram or the hydraulics sometimes provides this. When it doesn't, you'll need to do a few calculations to figure it out.

A few years ago, a motorcycle design and...

Readability is the focus of the PG10 digital pressure gauge. It is large enough to read well at a distance and it features a unique 270 degree bar graph that reads just like a traditional dial. The video below shows how to set up the bar graph:

Flow volume in open channels is an important measurement for any water management organization, especially in the water and wastewater industry. Furthermore, using an ultrasonic sensor for the measurement is a well established practice - one in which our LPU-2428 excels.

So how does it work? This video tutorial shows how to program the LPU-2428 ultrasonic sensor for open channel flow measurement. Let us know what you think, or if you have any questions.

The LPU-2428 can do all kinds of things, from open channel flow to submersible transducer replacement. However, it often needs to return to its roots and do some simple distance measurement. This quick video shows how to program the LPU-2428 for good ol' fashioned distance measurement.
