Sharky FS 473 — ultrasonic flow transducers for heat meters DN15–100, qp 0.6–60 m³/h, up to 150 °C
Country: Poland · Model: Sharky FS 473
Sharky FS 473 is an ultrasonic flow transducer for compact heat and cold meters in DN15–100 with nominal flows qp 0.6–60 m³/h. It works with a calculator, for example FAUN, and measures water from 5 °C to 130 °C (qp 0.6–2.5) or up to 150 °C (qp 3.5–60) at pressure up to 16 bar. It suits heating substations, metering stations of apartment and public buildings, and industrial heat consumers.

Description
The ultrasonic method gives stable measurements, low pressure loss, a low start-up threshold and a small minimum flow, and the instrument is insensitive to dirty water and scale. There are no moving parts, installation is permitted in any position, and straight sections before and after the transducer are not needed. The standard dynamic range is qi/qp 1:100, and for qp 1.5, 2.5, 6, 10, 15 and 25 m³/h a 1:250 range in class 2 is available on request. The range covers qp 0.6 (DN15, G¾B, 110 mm), 1.5 (DN15/20), 2.5 (DN20, G1B, 130 or 190 mm), 3.5 and 6 (DN25, G1¼B, 260 mm, and for 6 also a flanged DN32), 10 (DN40, G2B 200 mm or flange 300 mm), 15 (DN50), 25 (DN65), 40 (DN80) and 60 m³/h (DN100, 360 mm, 16.9 kg). The output is a pulse output of open-collector type with pulse weights of 1, 10 and 100 l/pulse, from 1 ml to 5 000 l/pulse depending on DN, cable 2.4 m (optionally 4.9 or 9.9 m). The environment class is EN 1434 C, MID E2 + M2, protection IP54 for heating and IP65 for cooling.
How to choose
The model is chosen by nominal flow qp and size. The 1:250 range in class 2 on request is available only for qp 1.5–25. If the water is hotter than 130 °C, the qp 3.5–60 versions are needed, which work up to 150 °C.
