LL4/LL5 - Hydrostatic

LL4-LL5 - Wireless Liquid Level Transmitter - Hydrostatic

LL4/LL5 – Hydrostatic

This wireless instrument determines level measurements by monitoring pressure at the bottom most point of vented top-mount tanks, deep wells, water towers and rivers.

The liquid level monitoring device is an ideal low cost solution when liquid temperature and densities are not changing. The LL4 direct mount version provides mounting solution and cable length is cut to customer specification. The LL5 multi-vendor version provides a junction box, terminal block, and retaining clip for making wiring hassle-free.

Description

OleumTech WT Series Wireless Liquid Level Transmitter – Hydrostatic is a self-contained, battery-powered liquid measurement solution made especially for the remote, rugged environments without access to a power line.

This device is part of the OleumTech Wireless Sensor Network.

This wireless instrument determines level measurements by monitoring pressure at the bottom most point of vented top-mount tanks, deep wells, water towers and rivers. The liquid level monitoring device is an ideal low cost solution when liquid temperature and densities are not changing. The LL4 direct mount version provides mounting solution and cable length is cut to customer specification. The LL5 multi-vendor version provides a junction box, terminal block, and retaining clip for making wiring hassle-free.

All WT Series Wireless Transmitters are equipped with a local LCD display that can be used for reading process data and for programming the device. Thus, cables and PC are no longer required for quickly setting up the device.

The Wireless Hydrostatic Liquid Level Transmitter is intrinsically safe (certified for use in Class I, Division 1 C1D1 Wireless (Zone 0) hazardous areas). It can be operated in a hazardous environment with or without the enclosure without the risk or fear of causing an explosion. This wireless end node transmits collected data to a Wireless Gateway that supports Modbus. The transmitter uses license-free, secure data transmission with a range of up to 7500 ft. Range (2.3 Km).
