LS-541-Liquid Level Switch

The LS-541 is intended to monitor the liquid level in a tank or vessel and provides a switched output for local alarm, pump or valve control. The differential between switching is equivalent to approximately 15mm. The unit mounts into 1” BSPT female boss. Access is not required to the inside of the tank.

From $195.41
LS-712-Hydrostatic Level Transmitter

Sontay’s new LS-712 range of submersible water level transmitters provides continuous hydrostatic level measurement up to 10.2m of water. They are suitable for many applications such as water tanks, wells, sumps and ponds. Transmitters have a vented cable which provides an atmospheric reference for the sensor, which is necessary for ensuring repeatable, precision depth measurements under the most adverse conditions.

From $1326.57
LS-AFS-Automatic Float Switch

The LS-AFS is designed for simple reliable water level control. The float switch can be used to control a pump for either tank filling or tank emptying (a high or low level cut-out). It is easily achieved by positioning the float stops on the cord. The electrical connections are easily made inside the housing, via the terminal strip. Two M20 cable glands are provided for use with suitable conduit.

From $144.28
LS-CAP-Capacitance Level Sensor

These sensors are designed for level measurement in tanks or sumps providing a 4-20mA output relating to the level of fluid in the tank. The LS-CAP1 is suitable for conducting liquids such as water whilst the LS-CAP2 is designed for use with clean, low viscosity non-conducting liquids such as oil.

From $1060.30
LS-FL-Multi-Level Switch

The LS-FL series is a range of level switches suitable for single or multi-level applications where access is only available from the top surface or where multiple level sensing is desired from a single penetration. Units consist of a float, which is suspended from a weighted cable. As the liquid level changes, the float follows the surface level, at the same time tilting due to its weighted restraint. Inside the float are a number of micro switches which trigger as the float tips.

From $192.97
LS-SN-Level Switch Side

A range of level switches designed for high and low liquid level detection in tanks and vessels. The LS-S types are for side mounting, type 1 switches fit from the inside of the tank and tighten on to a back nut whilst the type 2 switches mount from the outside into a tapered boss.

From $72.31
LS-SS-Stainless Level Switch Side Mount

A range of level switches designed for high and low liquid level detection in tanks and vessels. The LS-S types are for side mounting, type 1 switches fit from the inside of the tank and tighten on to a back nut whilst the type 2 switches mount from the outside into a tapered boss.

From $158.70
LS-TM-Reversible Top Mounting Level Switch

The LS-TM is an easy to install Top Mounting Level Switch, and has a reversible float so that it can be used for either high or low level alarms. The float is suspended from a 5 metre (16.4 ft) PVC cable with a polyethylene weight and is fully submersible and adjustable.

From $102.56
Ultrasonic Level Transmitter

The LS-UT provides accurate level measurement for liquids in tanks or sumps in applications where non-contact level monitoring is the preferred option. The 4-20mA loop powered output represents the distance between the surface of the liquid being detected and the transmitter. It has a user programmable measuring range of up to 8 meters, it works by sending out ultrasonic sound waves from its sensor, the sound waves reflect off the surface of the liquid in the vessel and return back to the sensor. The time taken to perform this process is calculated and then converted to provide a measurement in meters.
