The MultiTrode Probe has proven to be the most reliable and cost-effective liquid level sensor available.

How Does the Probe Work?
The Probe works by using the conductive properties of the water itself to complete a circuit with a controller. It’s mounted near the inflow, allowing the turbulence to keep it clean. Even if a build-up does occur it’s usually conductive (in wastewater) and so the Probe keeps right on working. When cleaning is required, the probe is installed off a mounting bracket that includes a cleaning device.

Why is it so reliable?
Ultra-reliable! No electronics and no moving parts means there is nothing to fail. That’s why it has a 10-year warranty! No other liquid level sensor comes close.

Why is it easier to install than other level devices?
All you do is hanging the Probe on its own cable into your wet well, using the bracket we supply. Installation is simple – any one of your technicians could do it in an hour or so. What’s more, you install the Probe relatively low down in the wet well. Compared to ball floats, it allows the well to be cleaned out more thoroughly. That means less debris build-up, odors and pump clogs.

Key Features

• Virtually no maintenance required
• Simple installation from outside the sump
• Easy visibility of start and stop points
• Unaffected by fat, oil, grease, debris and foam
• Excellent in turbulent sumps
• Safe, low sensing voltage
• Comes in a variety of lengths with 10-sensors, 3-sensors or single sensor.
• Custom sizes also available.

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current electric motor by controlling the frequency of the electrical power supplied to the motor. Variable-frequency drives allow operators to fine-tune their processes while reducing the cost of energy and equipment maintenance. 

VFD’s are quite useful to the water and wastewater industries because they can be used with the pumps, conveyors and drives involved in pumping and aeration applications. For instance, pumping uses excessive energy and cause significant wear-and-tear on equipment. Use of VFD drives enables pumps to accommodate fluctuating demand, running pumps at lower speeds and drawing less energy while meeting demand.

MultiTrode has developed an innovative VFD algorithm which makes it very easy to setup a VFD station. The standard application uses one 4-20mA control loop through each drive. The MultiSmart Pump Station Manager algorithm then provides a smooth power curve as levels are increased and decreased regardless of how many pumps come online.

For example, the lead (duty) pump starts at 50%, and at the level where it is running at 100% the lag (standby) pump starts. A lot of applications would start the lag pump at 50% and keep the lead pump at 100%. What the MultiSmart VFD algorithm does is start the lag pump and bring the speed of both to 75%. (And note that all of these parameters like start speed and level for 100% speed are user adjustable)

Therefore, multiple pumps will always be running at the same speed, and the speed will be adjusted depending on how many pumps are running.

Setup of this module is simple, with only the following values needing to be setup for each pump:

• Start speed, %
• Level at 100% speed

Some additional features help to optimize the station:

• Manual (hand) speed (to ensure that pumps run at full speed for manual/hand mode)
• Fixed speed value and duration if required, e.g. to clear pipes by running pumps at 100% for 10 seconds initially

There is nothing more refreshing than a cool tall glass of water on a hot summer’s day. This is such a small thing; it’s easy to take it for granted. After all, who doesn’t have clean water? If you ask UNICEF, the answer is – 1 billion people worldwide do not have access to safe water. Below is a list of charities that aim to lower that number. Together we can make a difference.

Water for People

“Water For People assists people in developing countries to improve quality of life by supporting the development of locally sustainable drinking water resources, sanitation facilities and hygiene education programs.” www.waterforpeople.org

 Water Aid

“WaterAid enables the world’s poorest people to gain access to safe water and sanitation. Together with improved hygiene, these basic human rights underpin health, education and livelihoods, forming the first essential step in overcoming poverty. We work with local partners, who understand local issues, and provide them with the skills and support to help communities set up and manage practical and sustainable projects that meet their real needs.” www.wateraid.org

 Water 1^st

“Water 1st’s mission is to serve families in the poorest communities in the world as they implement community-managed projects that integrate water supply, sanitation, and health education. We envision a world free of extreme poverty. Providing people with safe water systems, latrines, and hygiene education is the 1st step to ending the cycle of poverty and death.”  water1st.org

El Porvenir

“El Porvenir supports self–help, community–initiated water, sanitation and reforestation projects. Mission: To improve the standard of living of poor people in Nicaragua through sustainable self-help water, sanitation and reforestation projects.” www.elporvenir.org

 

Charity Water

“Almost a billion people on the planet don’t have access to clean drinking water. That’s one in eight of us. Charity: water is a non-profit organization bringing clean and safe drinking water to people in developing nations. 100% of public donations directly fund water projects.” www.charitywater.org

 

Water.org

Water.org is a U.S.-based nonprofit organization committed to providing safe drinking water and sanitation to people in developing countries. Our goals are to draw attention to the world’s number one health problem, unsafe and inadequate water supplies, and to raise funds to help fight this immense problem – one community at a time.” www.water.org

 

WaterLife

“WaterLife is a non-profit organization that exists to implement and support community-based, community-owned water and sanitation programs that offer dignity and opportunity to disadvantaged people worldwide.” www.waterlife.org

 

Water Charity

“The mission of Water Charity is to implement practical solutions to provide safe water, effective sanitation, and meaningful health education to those in need.” www.WaterCharity.org

 

Play Pumps International

“The mission of PlayPumps International – U.S. (PPI) is to help improve the lives of children and their families by providing easy access to clean drinking water, enhancing public health, and offering play equipment to millions across Africa.” http://blog.playpumps.org/home

 H2O Africa

“H2O Africa is the clean water initiative that is part of the “Running the Sahara” expedition and film project, now chronicled on a special DVD release. Co-founded by Matt Damon, H2O Africa is creating widespread public awareness of the water crisis in Africa and gathering support for clean water programs in critical areas, including communities along the Running the Sahara route.” www.h2oafrica.org Read more…
