The SiloPatrol model SMU provides substantially improved motor and cable strength and generates resolution of 100 pulses per foot. Monitor's SiloPatrol inventory-management system, launched in 1999, can monitor the level of materials in bins, silos, and tanks up to 150 ft high. "Whereas ultrasonics had been replacing the old weight-and-cable systems over the last 15 years, weight-and-cable is now replacing ultrasonic technology." Lewis says remote access and wireless communication capability (which cuts installation time and cost) have "re-energized" weight-and-cable technology. ![]() PC server software for controlling up to 128 sensors starts at $900, while software for remote computer access via wireless LAN, internet, or dial-up connections sells for around $500. For an additional $500 to $1000, you can get an alphanumeric control console. Monitor Technologies' Joe Lewis places the starting price for a cable-based "smart"-sensor unit at about $1100, including electronics and RS-45 two-wire cable. Isenhath cites industry estimates that some $160 billion/yr is spent on logistics, and the right tools-including level sensors-could shave 10% to 15% off that cost. Says Stan Isen hath, marketing manager at Kist ler-Morse, "Le vel sensing has be come a materials-management and logistics issue." He says level sensors there by contribute to better utilization of storage capacity and capital tied up in materials. of sales and marketing at Monitor Technologies. "More and more companies want suppliers to monitor their silos," observes Joe Lewis, v.p. Some of them offer new vendor-managed inventory programs, which take the burden off the processor to make sure the machine hoppers never run dry. Such information can be made available to purchasing, corporate management, and even raw-materials suppliers. Proliferation of networkable systems makes possible remote monitoring of material levels and other information, such as rate of usage, which can be extrapolated to predict when material will need replenishing before it is needed. These range from updated versions of simple, tried-and-true paddle switches and weight-and-cable monitors to new generations of more high-tech capacitance, radar, and laser systems. There is an expanding range of level-sensing technologies, and lots of new-product developments at all levels of sophistication. Today's level-detection instruments offer more choices than ever. Nor can they af ford wrong ans wers from inaccurate inven tory controls.įortunately, processors who store substantial quantities of bulk solid or liquid raw materials have a full kit of new tools to help them keep track of those pounds and gallons. How much material is left in your silo, bin, or bulk tank? Is there enough to finish the job run? How soon must you reorder? Plastics processors in today's environment of tight cost controls and Just-in-Time deliveries cannot afford to leave such questions unanswered. maker of laser level meters, says it can deliver sensors like the LM4C at one-third to one-half the cost of imported units.
