Wall Mounting Type Ultrasonic Flow Meter FM-23


Description : FEDREL Make Ultrasonic Flow Meter has wall mount meter The ultrasonic flow meter is composed by a digital converter. It is designed to measure the fluid velocity of a liquid inside a closed conduit. It is a art state-of-the-art universal transit-time flowmeter designed using SLSI technology and low-voltage broadband pulse transmission. While principally designed for clean liquid applications, the instrument is tolerant of liquids with the small amounts of air bubbles or suspended solids found in most industrial parts.
Linearity: Better than ±1%.
Repeatability: ±0.2%.
Velocity: ±0.03 ~ ±105 ft/s (±0.01 ~ ±30 m/s), bi-directional
Measurement Period: 0.5s
Display:LCD with backlight 2 x 20 letters
Keypad : 4x4-key membrane keypad with tactile feedback
Units: English (U.S.) or metric.
Outputs : Analogue output: 4-20mA or 0-20mA current output. Impedance 0~1kW. Accuracy 0.1%. Isolated OCT output: for frequency output (0~9,999Hz), alarm driver, or totaliser pulse output, ON/OFF control, etc. Relay output 1A@125VAC or 2A@30VDC. For ON/OFF control, alarm driver, totaliser output, etc. Internal Alarm (Buzzer): user programmable. External Alarm Driver: alarm signal can be transmitted to Relay or OCT output terminals to drive an external alarm. Enclosure Die-cast aluminum enclosure. Protection Class: IP65

Features and Benefits
  • Flowmeter cannot be affected by system pressure, fouling or wear.
  • Low power consumption, high precision, high reliability, high capability and low cost.
  • Clear, user friendly menu selection make flowmeter simple and convenient to use.
  • Almost- all universal measurement units worldwide may be selected to meet customer’s requirement
  • Daily, monthly, yearly totalized flow: Totalized flow for the last 64 days and months as well as for the last 5 years are may be viewed.
