No. SS2-MGN200-0200 Azbil Corporation - 2 - SPECIFICATIONS Overall specification Flow velocity range 0-0.3 to 0-10 m/s (Continuously adjustable) * Recommended upstream velocity condition: 1 to 4 m/s Accuracy (Combined with the MGG14C) * Recommended condition of use. Without dummy: Straight pipe section on the upstream side of detector is 3 times or over the nominal flowmeter diameter. With dummy: Straight channel section on the upstream side of detector is twice or more the water channel width Power supply (combined with MGG14C) 90 to 250V AC, 47 to 63 Hz 110A DC ± 10% 24V DC ± 10% Power consumption Approx. 10 W (Including detector and converter) Detector Material of body Rigid vinyl chloride (Parts in contact with fluid: SUS304) [Resisting (internal, external) pressure = 0.5 kgf/cm2] Materials of electrodes SUS316L, Titanium Structure Open channel type (equivalent to IP68 Underwater Type) Cables (10m for each cable) One 4-core shielded cable (outer diameter 11.4 mm; length 10 m) with cable protection vinyl tube (outer diameter 22 mm; length 10 m) Electrical conductivity of the measured fluid 5 μS/cm or over Ambient temperature limits 0 to 40°C Weight 50 mm (detector; 10 kg, dummy; 1.4 kg) 400 mm (detector; 130 kg, dummy; 33.4 kg) 100 mm (detector; 23 kg, dummy; 3.4 kg) 600 mm (detector; 220 kg, dummy; 59.4 kg) 200 mm (detector; 45 kg, dummy; 10.4 kg) Average flow velocity of detector (m/s) V = K × Q [V: Flow velocity (m/s), Q: Flow rate (m3/h), K: Flow velocity conversion coefficient ] [Example] Detector size: 200 [mm], Flow rate per detector: 250 [m3/h] V = K × Q = 0.008842 × 250 = 2.21 [m/s] Water level calculation (bell mouth type) Conversion of water head differential (H1) to water level H1 = K1 × V2 in which K1: Water head differential conversion coefficient 0.053 (Example) When the average flow velocity of a detector is 2.21 [m/s] H1 = K1 × V2 = 0.053 × (2.21)2 = 0.259 [m] Conversion of overflow water depth (H2O) to water level H2 = (Example) When the maximum flow rate is 500 [m3/h] and sheathing board width is 2 [m] H2 = = = 0.113 m Within the recommended condition* Out of the recommended condition When detector is used without dummy or dummies ± 1.0% F.S. ± 2.0% F.S.
