Polcon® Sentry Recorder The Polcon® Sentry Recorder is a totally unique solid state microprocessor type recorder that senses, gathers, stores, and processes differential pressure form your pitot rod. The Sentry generates a 4-20mA signal using a Rosemount differential pressure transmitter along with a Telog recorder. The recorder can be set to measure twenty four-hour flows from 1 day (with a sampling period of one minute) to 7 days (with a sampling period of five minutes) on a single set of batteries. The Sentry is self-contained, has its own power pack, weighs less than 30 lbs., and fits into the standard 20.25" manhole entrance. Included with the Sentry is an extra set of batteries, a battery charger, a 3’ connector cable, and an operation manual. Data is "downloaded" using a laptop computer with software provided. All data can be permanently stored on the computer’s hard drive or floppy disk. The data can also be exported to a spreadsheet program, such as Microsoft® Excel, so the data can be analyzed and reviewed with the Polcon® spread sheet forms. With this process you eliminate manometers, toxic indicating liquids and manual entries.
The Polcon® Pacer "state-of-the-art" pressure recorder is a self-contained microprocessor that senses, gathers, stores, and processes data every second. We use an Ashcroft pressure transducer (0 – 150 psi) along with at Telog recorder. With this recorder you can generate maximum pressures, minimum pressures, average pressures, times of occurrence, and produce graphs of the pressure. You will no longer need to worry about pens, inks, charts and other related material like the old pressure recorders. Data is "downloaded" using a laptop computer with the software provided. All data can be permanently stored on the computer’s hard drive or floppy disk. The data can also be exported to a spreadsheet program, such as Microsoft® Excel, so the data can be analyzed and reviewed with the Polcon® spread sheet forms. Polcon® Pitot Rod The Polcon® Pitot Rod is constructed completely of high-grade brass to insure a device that is durable as well as accurate. Our "O" ring packing and locking device assures that all Polcon® Pitot Rods will provide a safe and leak proof installation. Our solid orifice plate assures the upstream and downstream orifices remain in the same plane and directly opposite one another, which gives you an accurate measurement of the velocity in the pipe. Polcon® Pipe Caliber The Polcon® Pipe Caliper is constructed with high-grade brass and steel to insure a device that is durable as well as accurate. Our "O" ring packing and locking device assures that all Polcon® Pipe Calipers will provide a safe and leak proof installation. The caliper is used for the accurate determination of pipe diameter to obtain the true Q=AV relationship. The inside diameters are always taken to the 1/16-inch to maintain the true integrity of the hydraulic data. The unique design permits accurate determination of the pipe diameter even if the tap extends through the pipe wall.
