New sensors provide improved accuracy

The Blackwater Level Sensor 7014 features technology that uses a simple probe and no moving parts to provide accurate solid waste level measurement. This design eliminates the problem of solid waste build up on sensors that cause frozen output(s). With no moving parts or floats, there is nothing to wear or freeze for maintenance-free performance.

The 7014 probe's FEP (Fluorinated Ethylene Propylene) surface acts as the sensing surface. Using Gill's proprietary capacitive technology, the sensor can differentiate between solid waste coming into contact with the probe's exterior surface versus air (unfilled space at the top of the tank). 

The difference between the two is used to calculate true level for optimum accuracy. The sensing surface is equally effective at angled measurement where conventional access is not possible. The sensor's wetted FEP probe is immune to not only solid waste, but also common detergents, paper products, odor masks and other aggressive cleaning chemical combinations commonly found in the waste stream.

Unlike other level sensing solutions on the market, Gill provides customisation using easy to use GUI software. Users can set both minimum and maximum levels and use the tank sensor profiling feature to linearise the output on non-standard tank geometries. Software also includes a programmable switch function (output) that allows users to set either a specific level to trigger an alarm or a warning that the tank's level has reached the preselected point. 

The sensor is available in sizes from 250-2,000mm with all of the electrical outputs including Resistive 10-180Ω or 240-33Ω,  Analogue with both  0.25-4.75V DC and 0.25-10.0V versions, and Current Output with 4-20mA.

"We are excited to bring a new sensing technology to difficult black and gray water applications," said Paul Cain, Manager of Business Development for Gill Sensors North America.  "With  this sensor, users can 'install it and forget it' while obtaining a more reliable signal,  Additionally, the tank profiling software is ideal in obtaining gauge readings where ½ tank indication truly means 50% capacity remaining."
