Portable flow meter

Series DMTFP Portable Transit Time Ultrasonic Flow Meter is a state-of-the-art universal transit-time flowmeter using MultiPulseTM technology and low-voltage broadband pulse transmission, feature the worlds advanced non-invasive flow measurement technology providing a measuring system with unsurpassed accuracy, versatility, ease of installation and dependability. Although designed primarily for cleaner liquids, the flow meter can reliably measure liquids containing moderate amounts of suspended solids or aeration. DMTFP is designed for long or short term flow measurement surveys on full-pipe liquid systems and is ideal for verifying calibration of permanently mounted flow meters of all types.

Applications：

u  Water (hot water, cooling water, potable water, sea water etc.)

u  Petroleum products

u  Chemicals, including alcohol, acids, etc

u  HVAC, energy measurement system

u  Beverage, food and pharmaceutical processors

u  Secondary sewage, waste treatment, etc.

u  Power plants (nuclear power plants, thermal & hydropower plants), heat energy boiler feed water.

u  Metallurgy and miming applications

u  Pipeline leak detection, inspection, tracking and collection

u  Network monitoring

Features:

1. Non-invasive transducers are easy to install, cost effective, and require no pipe cutting or processing interrupt. Since the transducers do not contact with the liquid, fouling and maintenance are eliminated.

2. Standard and Explosion-Proof ATEX (ExdIIBT6; LCIE 09 ATEX 3008) transmitters are available, Wide liquid temperature range: -40℃~250℃.

3. Remote operation by the wireless handheld operator. No matter the pipeline in high altitude or underground, users can install or adjust the transducers more convenient.

4. The wireless handheld operator has wireless remote reading function and it also can operate the meters instead of panel operations.

5. Built-in large capacity memory and USB data download function. The downloaded data can be opened by EXCEL directly.

6. The heat measurement function by configuring with paired Pt1000 temperature sensors.

7. Wide range of pipe sizes from DN20 to DN4500.

8. Wide bi-directional flow range of 0.003 m/s to 12 m/s.
