SXLV Variable Liquid Level Sensor
GrowControl™ SXLV continuous liquid level sensor: measures water depth through a 1 in PVC pipe, up to 10 ft (SXLV-10) or 30 ft (SXLV-30), for GCX or MODBUS.
Continuous Liquid Level Sensing
Monitor and control liquid level in water tanks, reservoirs, bucket systems, ebb and flow trays, stock tanks and more with GrowControl™ GCX controllers or MODBUS RTU.
Only a 1 in PVC pipe touches the water. The SXLV sits on top of the pipe, measures the pressure inside it as the level rises and falls, and converts that into an accurate water height.
How It Works
The SXLV measures water depth from the end of the tube.
- Green LEDs: water level is above the bottom of the tube.
- Yellow LEDs: water level is below the bottom of the tube.
- Includes a threaded socket-weld fitting for 1 in PVC; PVC pipe not included.
- Available with a PVC mounting flange for bolting to the top of a tank.

Installation
Glue the threaded fitting to the end of a standard 1 in PVC pipe with PVC primer and cement, then screw on the sensor head. Connect the sensor to the control system, fill the tank, and calibrate the depth reading when the tank is full.
Models
SXLV-10
Standard depth: maximum water depth 10 ft (3 m).
SXLV-30
Extended depth: maximum water depth 30 ft (10 m).
Connect it
Use it with a GrowControl™ GCX, or with PLCs and building automation over MODBUS.
