ULTRA OVAL for Remote Measurement

Format:LUS

Liquid

Gas

Steam

The ULTRA OVAL for remote measurement with the small pulse generator is designed to make remote flow measurement or central control easy.
This reliable model is used in various applications where high-accuracy measurement at low flowrate is required, such as laboratories and production processes in chemical, pharmaceutical, food, pollution prevention, and paint industries.

FEATURES

1. Pocketless design of measuring chamber construction makes the flowmeter ideal for fine chemicals, foods, pharmaceuticals, cosmetics and etc., furthermore, simplifies maintenance and inspection work.
2. Flowrate information is transmitted by the pulse generator in the form of a noncontact pulse signal compatible with highly sensitive and reliable remote instrumentation.
3. Absence of any mechanical transmission requires no loss in torque and ensures long service life.
4. Flow totalizing and instantaneous flowrate indication are monitored in a LCD counter independently mounted.
5. Explosion-proof approved (TIIS, NEPSI)
