Series DMTFC Insertion

Series DMTFC wall-mounted Insertion Transit Time Ultrasonic Flow meter provides abundant capabilities for accurate liquid flow measurement from outside of a pipe. It utilizes state-of-the-art technologies on ultrasonic transmission /receiving, digital signal processing and transit-time measurement. The proprietary signal quality tracking and self-adapting technologies allow system to optimally adapt to different pipe materials automatically. Due to hot-tapped mounting of insertion transducers, there is no ultrasonic compound and coupling problem; Even though the transducers are inserted into pipe wall, they do not intrude into the flow, thus, do not generate disturbance or pressure drop to the flow. The insertion (wetted) type has the advantage of long-term stability and better accuracy.

Features:

1. Hot-tapped installation, no pipe line flow interrupted.
2. Internally configured batch controller makes batch control convenient and accurate.
3. Spool-piece transducer for best accuracy (better than ±1.0% read) and better long-term stability.
4. No moving parts, no pressure drop, no maintenance.
5. Wide bi-directional Flow range of 0 to 40 ft/s (0 to 12 m/s), totalizer for net, positive and negative flow display. One meter suitable for a wide range of pipe sizes from DN65 to DN4500.
6. Signal quality tracking and self-adjusting functions.
7. Available with extended insertion transducers for cement pipe line, wall thickness less than 100mm permitted.
8. Up to 8GB SD card data logger optional, can memory flow rate, total flow, velocity and time. Time interval can be freely setup by user.
9. Insertion transducers are suitable for high temperature of -40℃~150℃.

Applications:

1. Water, including hot water, chilled water, city water, sea water etc.

2. Secondary sewage, waste treatment, etc.

3. Oil, including lubricating oil, diesel oil, fuel oil, etc.

4. Beverage, food and pharmaceutical processor

5. HVAC, energy measurement system, etc.
