This document introduces the four models of Flowline Switch-Tek™ powered level switches, including Vibration (LZ12 series), Ultrasonic (LU10 series), Optic Leak (LO10 series) and SuperGuard Capacitance (LP15 series), and details the characteristics of each model.
This document provides instructions for Flowline Switch-Tek™ Powered Liquid Level Switches, covering four specific models: the Vibration type (LZ12), Ultrasonic type (LU10), Optic Leak Detection type (LO10), and Capacitance type (LP15). All series feature two outputs: a 4-20 mA current switch and a 60VA SPST dry contact relay. They are manufactured with thermoplastics for submersible use in corrosive environments.
| Supply voltage | 12-36 VDC (LZ12 Only: 12-30 VDC) |
|---|---|
| Contact rating | 60VA (125 VAC max / 1A max) |
| Process temperature | -40° to 176°F (-40° to 80°C) |
| Pressure rating | 150 psi (10 bar) @ 25 °C. |
| Sensor rating | NEMA 6 (IP68) |
The LP15 series is factory-calibrated for liquids with a dielectric value between 20 and 80. Liquids with a dielectric constant less than 20 will not be detected.
It operates at a nominal frequency of 400 Hz; immersion in liquid causes a frequency shift that indicates the presence of the medium.
It outputs an alarm when material buildup prevents the vibration switch from operating at its operational frequency.
