DESCRIPTION
Features

Float Level Probe for Small Tanks

The RPE General Use Resistive-Chain Probe Level sensor is designed for small tanks up to 12.75 ft. in height. This highly durable float level probe offers exceptional chemical compatibility and is customizable to fit your exact application needs. It features a simple float-based operation (“float-goes-up, float-goes-down”), making it less prone to performance interruptions and inaccuracies.

The RPE level probe excels in tough applications, including mud tanks and wastewater systems. It provides a reliable solution for measuring thick, viscous, or sludgy fluids.

Customizable: Customizable stem length, float size, and specific gravity
Versatile Connection Options: Available with 4-20 mA or resistive output
1/2" Stem: 1/2" stem for small tank applications
Housing Choices: Choose between Nylon or Aluminum housing

Can the RPE transmitter be customized for my application?

Yes, the RPE level probe can be customized in terms of stem length, float size, and specific gravity to fit your exact application requirements.

Does the RPE transmitter require calibration?

The RPE transmitter is designed for simple and reliable float-based operation. While initial setup may require calibration to match specific tank levels, ongoing recalibration is generally minimal.

Is the RPE transmitter suitable for wastewater and sludge applications?

Yes, the RPE transmitter is specifically designed to handle thick, viscous, and sludgy fluids, making it ideal for wastewater treatment, sewage, and mixed effluent applications.

How do I install and maintain the RPE level transmitter?

Installation is straightforward, with mounting options tailored to your tank setup. Maintenance is minimal due to its simple float-based design, but periodic inspections are recommended to ensure optimal performance.
