Flow sensor 210 0.5 ... 150 l/min

Product catalog summary

Overview: The Huba Control Type 210 flow sensor utilizes the Kármán vortex trail principle, offering improved power supply and output signals over the OEM Type 200. It is designed for liquid media and can include temperature measurement capabilities.

Key Features:

Resistant to debris with no moving parts, ensuring high accuracy and minimal pressure loss.
Output options include voltage, current, pulse, or frequency.
Temperature measurement range from -40 to +125 ºC.
Approved for drinking water applications (KTW, W270, ACS, WRAS).

Specifications:

Flow range: 0.5 to 150 l/min.
Nominal diameters: DN 6, 8, 10, 15, 20, 25.
Accuracy: Less than 1% fs for under 50% fs and less than 2% measuring value for over 50% fs.
Response time: Immediate for spigot use, with a signal delay of less than 100 ms for unfiltered frequency output.

Operating Conditions:

Suitable for heating circuit water and other media upon request.
Maximum media temperature: +125 ºC; ambient temperature: -15 to +85 ºC.
Pressure ratings vary with temperature, up to 18 bar at +40 ºC.

Materials and Compatibility:

Sensor paddle made of ETFE; case with damming body made of PA6T/6I (40% GF).
Sealing materials include EPDM and FPM.
Electrical connection via M12x1 connector, IP 65 protection standard.

Electrical Specifications:

Power supply ranges from 4.75 to 33 VDC depending on output type.
Output options include analogue signals (0-10 V, 4-20 mA) and frequency outputs.
Includes short circuit, reverse voltage, and external voltage protection.

Accessories:

Connection kits available for various DN sizes with copper tubes or adapters.
Various O-rings and clips for different DN sizes.

Installation Guidelines:

Ensure correct sensor function by allowing only diameter changes from large to small.
Avoid repeated elbows at the entry side; recommended minimum distances provided.

Technical Specifications: Detailed specifications for connection tubes and accessories with diameters DN 8, 10, 15, and 20, including precise measurements for each diameter.

Electrical Connections: Descriptions of various electrical connections, including connectors with and without temperature measurement capabilities, current and voltage output configurations, and frequency and pulse outputs. Specific pin color codes and connection diagrams are provided.

Flow Measurement Formulas: Includes formulas for calculating flow rates based on frequency, impulse, and voltage outputs for different diameters (DN10, DN15, DN20, DN25), as well as formulas for current output in mA.

Viscosity Influence: Discusses the impact of media viscosity on measurement accuracy, particularly for media with higher viscosity than water, and provides corrections for kinematic viscosity of ethylene glycol-water and propylene glycol-water mixtures.

Graphical Data: Graphs illustrate the relationship between viscosity and temperature, minimal detectable flow, and the influence of viscosity on flow measurement accuracy.
