The fixture is a lightweight, compact device comprising a sensor that can be fitted to a pipe of variable diameter, and a remote digital converter.
M-Flow PW stationary ultrasonic flowmeter
Compact and lightweight flowmeter
This ultrasonic portable flowmeter consists of a detector clamped on the pipe (DN25 to 1200 mm depending on detectors) and of a and of a digital converter mounted remotely.
It can measure bi-directional flow speeds from -10 to +10 m/s.
Features
High accuracy : ±1,5% of rate
Quick response time : < 0.2 sec
Compact : 130 x 140 mm
Output signal : 4-20 mA, pulse output, alarm output
Communication : RS485 MODBUS™ option
Operation can be performed from the outside panel
A display and a built-in keypad allow the user to configure and view all parameters.
Internal menus are available in several languages (English, French, German, Spanish and Japanese).
The FSS is designed to measure homogeneous liquids capable of propagating ultrasonic waves, including service water, waste water, industrial water, seawater, pure water, irrigation water, oil and many others. This versatility makes it ideal for a wide range of industrial applications.
Ultrasonic Transit Time Difference Measurement
The FSS uses a single-channel transit time difference ultrasonic measurement method, guaranteeing optimum accuracy even under variable conditions.
Sensor and piping selection
The FSS offers different sensor options depending on the type of installation, external diameter and pipe material:
FSSA (V-mount): 25-225 mm - Plastic (PVC, etc.) or Metal (stainless steel, steel, copper, aluminium, etc.)
FSSC (V-mount): 50-600 mm
FSSC (Z-mounted): 600-1200 mm
All three sensors work with plastic (PVC, etc.) or metal (stainless steel, steel, copper, aluminum, etc.) materials.
Please note that the FSSC sensor must be selected for the following pipes:
PP pipe with a thickness of 15 mm or more
PVDF pipe with a thickness of 9 mm or more
Coated metal pipe, pipe with internal corrosion, pipe with internal coating (bitumen, Teflon, cement or rubber), or other pipe through which ultrasonic waves have difficulty penetrating.
Range and Accuracy
The FSS offers a measurement range from 0 to ±0.3...±10 m/s with exceptional accuracy of ±1.0% of velocity (for flow velocities ≥2 m/s).
Operating temperature and response time
The sensor operates over a wide temperature range:
Converter: -20°C to +55°C
Sensor: -20°C to +60°C...80°C (sensor-dependent)
With a rapid response time of 0.2 seconds in high-speed mode, the FSS offers optimum responsiveness in dynamic conditions.
Outings and Communication
The FSS offers a variety of outings for easy integration:
Analog output: 4-20 mA DC (max. load: 600Ω)
Contact output: Open collector, 2 points (total, alarm, etc.)
Pulse output: Total - 1 Imp./day to 100 Imp./sec. (open collector)
Serial communication: RS-485 (MODBUS) (optional)
Display and power supply
Featuring a 2-line, 16-digit backlit LCD display, the FSS offers a user-friendly interface with a 4-key keypad. Powered by 100-240 V AC, 50/60 Hz, or 20-30 V DC, it provides a stable power supply.
Converter box and mounting
The ABS resin converter housing provides IP65 protection, withstanding harsh industrial environments. It can be wall- or tube-mounted, offering installation flexibility.
Compact dimensions
The converter features compact dimensions of H140 x L130 x D70 mm, optimizing installation space.
