Original Press Release:

Level Mate III Liquid Level Measurement System Combines Simplicity, Versatility and Accuracy in Low-Cost, Easy-to-Use Liquid Level Measurement System

Complete Hydrostatic Level Measurement Solution Is Ready to Use Out of the Box

FEASTERVILLE, PA-New Level Mate III from AMETEK PMT Products provides the most versatile and complete level measurement system for water and waste water applications. The Level Mate III system consists of a rugged stainless steel submersible AMETEK hydrostatic sensor with cable and a fully calibrated microprocessor-controlled digital meter within a rugged NEMA 4X enclosure. Installation is simple requiring minimal time and effort.

All programming is done at the factory so users only need to supply AC power to the unit and place the sensor in water.

The Level Mate III comes with all of the necessary features and accessories for a complete system. Standard features include a two-line LED display meter with configurable function keys, engineering units, programmable 3A Form C relays, analog output, alternating pump control, and 32-point linearization programs. Installed desiccants are included for moisture control. Among the unit's options are AC & DC, lightning and surge protection, additional relays, stainless steel support cable and choice of multiple sensors based on application requirements. In addition, the system is backed by a two-year warranty and AMETEK's more than 50 years of experience in providing process level measurement solutions.

At the heart of the Level Mate III is an AMETEK's hydrostatic pressure sensor connected to the Level Mate III enclosure via waterproof, flexible cable. The piezoresistive technology within the transmitter indicates liquid level by continuously measuring hydrostatic pressure through the transmitter's nose-mounted sensing element. The result is an extremely high level of accuracy and reliability. The device operates in depths from 3feet to 690 feet (211 meters) and at pressures up to 300 psi, depending on choice of sensor.

The customizable meter on the Level Mate III provides excitation voltage, displays data from the transmitter, and transmits an analog signal for remote recording, alarm or control functions. The independently programmable, easy-to-read, two-line digital display gives local indication, while an isolated 4-20 mA analog output can interface with an ancillary display, recording or control devices. Two standard relays are provided for pump control or alarm activation with 0-100% deadband setting capability on each.

Hydrostatic pressure technology is among the oldest forms of level measurement technology and can be used for a wide range of applications from basic well-level measurement to sophisticated process tank level control. Unlike mechanical systems, such floats and bubblers that require extensive maintenance, the Level Mate III offers simple installation with virtually no maintenance.

The simple design and rugged construction of the solid-state Level Mate III provides long-lasting service with virtually no maintenance. All of the transmitter's electronics are mounted in submersible 316 stainless steel housing. The transmitter has a removable, non-clogging snub nose end and is available with a flush diaphragm or protective "shark cage" enclosure. A special cable support bracket is available that gives extra stability to the transmitter when used with longer lengths of cable or when used in an agitated liquid. The instrument is vented to the atmosphere through the surface end of the cable through a desiccant cartridge to keep moisture out.

The Level Mate III is a cost-effective alternative to other electronic devices, such as capacitance sensors, conductivity probes, ultrasonic or radar devices. Hydrostatic technology is able to measure hundreds of feet of water head pressure and is independent of tank obstructions. There also is no need for tank mapping or special compensation due to variously sized tanks and wells. In addition, the technology ignores foam buildup on the water's surface that can cause measurement errors for other technologies.
