Low-level alarms for buckets and drums ensure that processes never run out of chemicals. When the liquid level drops below the protected float switch, the alarm emits a loud buzzer sound and flashing LED. The alarms include a long-lasting lithium-ion battery for years of uninterruptible use and a low-battery alert. Adjusting the depth of the alarm is done by simply loosening the thumb knob on the lid and positioning the pipe to the desired depth by hand. The float switch is protected inside the pipe from physical damage, making it easy to store and transfer to another container. For manual systems, the alarms without suction pipes are an excellent option. These models have a 3/4" threaded drum plug mount, which is more securely attached and can shield the drum opening from debris and suppress noxious vapors. Kynar® PVDF and stainless steel versions of the low-level alarms and accessories, including an AC power cord, 30-minute silencer button, relay output, and wireless transmitter/receiver, are available; contact us for a quote.
