Thiết bị đo lưu lượng ISM Greyline

electromagnetic with no moving parts
simplified hot tap insertion design
installs in 3-72" (80-1800 mm) diameter pipes
selectable 4-20mA, 0-5V or 0-10V output
0-500Hz frequency output
scalable pulse output

Provide a Greyline ISM 5.0 Insertion Magmeter complete with all installation hardware necessary to enable insertion and removal of the meter without system shutdown. The flow meter shall be hand-insertable up to 400 psi. For installations in non-metallic pipe, install grounding rings or probes. Materials of construction for wetted metal components shall be 316 SS.  The flow meter shall average velocity readings from two sets of diametrically opposed electrodes.  Each flow meter shall be individually wet-calibrated against a primary volumetric standard that is accurate to within 0.1% and traceable to NIST*.  A certificate of calibration shall be provided with each flow meter. Accuracy shall be within ± 1% of rate from 2-20 ft/s. Overall turndown shall exceed 100:1.

Output signals shall be completely isolated and shall consist of the following: (1) analog output; 4-20mA, 0-10V, or 0-5V jumper selectable, (1) scalable dry contact output for totalization, and (1) high resolution frequency output for use with peripheral devices.  ISM 5.0-B for Bi-directional applications shall provide additional contact outputs for direction and flow totalization in each direction. Each flow meter shall be certified to NSF Standards and covered by the manufacturer’s two-year warranty.
