MJ-SDC multi-jet water meters are available for ¾- to 2-in. pipe sizes. They are dry dial-type totalizing water meters, offered with pulse switch outputs of one pulse per 0.1, 1, 10 or 100 gal. A 59-in. length of two-conductor wire, 3.5-mm diameter, is standard. The main casing is made of ECO brass, and the maximum operating temperature and pressure are 122°F and 150 psi, respectively. The meters comply with NSF/ANSI standards 61 and 372, and conform with lead-free plumbing regulations.
The Sonic-Pro S4 inline ultrasonic flowmeter measures flow using the Transit Time method. The technology has no moving parts and no internal liners. Pipe fittings facilitate installation of the meter, and a special low power mode permits operation with battery for limited functions. Download data logging files directly to a flash drive via USB. The flowmeter is NSF 61 certified and the housing is NEMA 4X/IP 66 for wash-down.
The YSI Pro1030 handheld meter measures pH or ORP, plus temperature, conductivity, specific conductance, salinity and TDS. It has user-replaceable pH and ORP sensors, cables and a convenient calibration. Its ruggedness is backed up by military-spec connectors, IP67 waterproof and rubber over-molded case, and 1-meter drop tests. A four-electrode conductivity cell is built into the cable and requires minimal maintenance.
The new AquaPro digital water tester (model AP-1) is a TDS meter designed for today’s modern world. The meter features a large horizontal display, wide range, on-screen temperature display, digital calibration and water-resistant housing. It also includes a chart on the back explaining what the TDS values represent. This patent-pending meter is backed by a one-year factory warranty.
By integrating water meter data recorders as SCADA system RTUs, Massachusetts Water Resources Authority (MWRA) is making field crews more efficient and getting indications of problems within seconds.
