Vortex Shedding Flowmeter

Product catalog summary

Description: The Vortex Shedding Flowmeter is designed for water, water/glycol coolant, or low viscosity fluids. Key features include a 4-20 mA flow transmitter, configurable solid-state relay for alarm set points or pulse output, LED digital display, and no moving parts to prevent clogging or wear. It is CSA and CE certified, with an optional temperature transmitter.

Electrical Specifications: The flowmeter requires an input power of 10 - 30 VDC at 80 mA. It outputs a 4-20 mA signal with 25 pulses per gallon from the solid-state relay. Electrical connections include a standard pin connector, optional pigtails, or a junction box with a terminal strip.

Material Specifications: The flow bodies are made of brass with PVDF sensors and Viton® seals as standard.

User-Configurable Options: Users can select features such as alarm state (normally open or closed), set point or pulse output, and engineering units (GPM, LPM). The control box is rotatable for all units.

Instrument Specifications:

Flow: Visual readout with a 3-digit LED, response time selectable from 0.9 to 7.5 seconds, 5% F.S. deadband alarm, accuracy of ±2% F.S., repeatability of ±0.25% of indicated flow, and a turndown ratio of 10:1.
Temperature (CT units only): Response time of 1.8 seconds, ±2% deadband alarm, accuracy of ±1% F.S., repeatability of ±0.25% of indicated flow, and output of 4 mA at 32°F to 20mA at 210°F linearly.
Pressure: Operating pressure of 200 PSIG (13 Bar).
General: Fluid temperature limits are 35-210°F (2-99°C), with a high-temperature option extending to 225°F for one hour. Enclosure rating is IP 65, Type 1, 3, 4, 12, and 13.

Pipe Connections: ANSI Class 150 R.F. Flanges are available for CP models with 3-4 inch sizes, flow range of 300-600 GPM (1136-2271 LPM), and maximum pressure of 200 PSI (13 Bar).

Model Codes and Ordering: Standard models have fixed flow rates for each pipe size, brass construction, Viton® seals, and 4-20mA output with programmable set point or pulse out selectable. Special options require additional symbols in the model code.

Pressure Drop Charts: Charts are provided to illustrate pressure drop across different flow rates in GPM and LPM.

Installation and Pin Configuration: Detailed installation drawings and pin configurations are provided for both CP (flow only) and CT (flow and temperature) models, including pin assignments for power supply, flow signal, and relay contacts.
