POEM’s solar-powered cellular tank monitors require zero maintenance ever, for the lifetime of the device. POEM offers several payment options, including a plan with no monthly fees. Integrated TankVue software provides a complete snapshot of your tanks and monitor status. In these times of social distancing, installation only requires access to the tank. No routers and no passwords keep installation safe and easy. Call Arnold Stillman at 8447636832 or email at [email protected].
