Water & Wastewater: Pumping station control, leakage detection, and overfill prevention in storage tanks.
Food & Beverage: Level monitoring in hygienic mixing tanks, hoppers, and bottling lines.
Chemical & Pharmaceutical: Safe level detection in corrosive liquid tanks and powder silos.
Mining & Cement: Monitoring bulk solid levels in silos and conveyors to prevent blockages.
Oil & Gas: High-level alarm systems and separator level control in upstream and downstream facilities.
HVAC & Utilities: Chiller loop level monitoring and expansion tank control.
A point-level switch detects if a material has reached a specific target level (High/Low alarm), whereas a continuous sensor provides real-time data on the exact level throughout the entire range of the tank.
Yes, though for extremely sticky media, we recommend choosing our vibrating fork or specially coated capacitive level switches to prevent false triggering from material buildup.
Our standard electronic level switches require a 24VDC power source. However, we also supply passive magnetic float switches that can operate as simple dry contact closures in certain applications.
As a versatile supplier, we serve various sectors including chemical, water treatment, food and beverage, and cement industries. Our robust designs are adaptable to both liquid and bulk solid environments.
