SPI-73 Flow Meter, Totalizer

Introducing the SPI-73 Flow Counters, the optimal choice for working with flow transducers featuring contact or electronic inputs. These counters offer precise measurement and recording of both instantaneous and total flow for liquids, gases, or loose materials. They provide extensive total flow indication with up to 16 digits, ensuring accurate monitoring over extended periods. Programmable REL/OC control outputs cater to instantaneous flow, batcher, or total flow, enhancing operational control. Configuration is straightforward with the local keyboard or S-Config software through RS-485. Elevate your flow measurement with the efficient and accurate SPI-73 Flow Counters.

Product Highlights

The SPI73 flow counters are specifically engineered to function seamlessly alongside flow transducers featuring contact or electronic inputs. These counters serve the crucial role of accurately measuring the instantaneous flow value while simultaneously recording the overall flow of various media types, including liquids, gases, and loose materials. With a remarkable total flow indication range of up to 16 digits, they offer exceptional control over flow values throughout extended operational periods. The counter’s REL/OC control output can be conveniently programmed based on factors such as the instantaneous flow value, batcher specifications, or total flow value. Moreover, configuring the counter is a breeze, whether through the intuitive local keyboard or the user-friendly S-Config software, which is available free of charge. This configuration process can be effortlessly accomplished using the RS-485 communication port, further enhancing the counter’s versatility and ease of use.
