247 dp indicator
M247 functions: Pressure Overrange Protection (up to 500 PSI)–no meter harm owing to peaks. Easy learning–150 distinct 0.1 PSID divisions label the big scale. 246 BFT’s tiny 3-inch scale is a compact tester. 247 BFT’s big6-inch scale offers simple learning. Five easy-to-use tubes–engineered with tubular metal, corrosion-resistant, tubes and smooth seats. Unique built-in tube–allow a stress gage to be added to achieve continuous stress viewing during experiments.
Compact case (steel-reinforced polyethene) with fabric plug–minimizes storage harm. Adaptable –enables efficiency on all backflow meetings. Hand / shoulder brace–enables field use included fittings / hoses–sample fittings and three colour tagged,6-foot hoses for simple hookup. Using the welded beryllium copper bellows installation, these testers are precise to one-half of one third, converting a measurement in increasing and falling activities within 0.075 PSID.
