Optimass Mass Flow

Meters

KROHNE offers a wide variety of process measurement instruments. In fact, we invented quite a number of them. We offer supporting products and services for 1-stop-shopping and in industries as widespread as oil and gas, water, chemicals, pharmaceuticals, food & beverages, mining and shipping.

The H 250 flowmeter for measurement of the volumetric or mass flow rate of liquids, gases and steam is an all-metal flowmeter that operates on the float measuring principle. The flow-dependent vertical position of the float in the measuring tube is transmitted by a magnetic coupling system to the scale in the indicator part. The flowmeter is installed in a vertical pipe run, with flow from bottom to top. Owing to its rugged design, the H 250 variable-area flowmeter is particularly suitable for difficult applications and environmental conditions.

In the M9 indicator, the vertical position of the float is transmitted to the pointer/ magnet system, and the flow value indicated directly on the scale.

- Simple, rugged design
- Particularly suitable for use with highly corosive, noxious or flammable substances and ideal for severe operating conditions
- For Level or Interface measurement
- Measuring tube for pressures up to 120 bar / 1740 psig and temperatures up to 300°C / 570°F
- Easily read scale for level readings, no power required
- Limit switches (option) suitable for mounting
- (MS 15 or MS 20)
- 3 different types of protection (STD, EXI or EXD)

BM 26 F | BM 26 W

BM 26 F integrates the OPTIFLEX 1300 C Guided Radar (TDR) Level Meter for distance, level and volume measurement of liquids and liquid/liquid interface.

BM 26 W integrates the OPTIWAVE 7300 C FMCW Radar Level Meter for distance, level and volume measurement of liquids. It can measure level in a variety of difficult conditions.

Measuring principle

The BM 26 A operates on the principle of communicating vessels. The measuring chamber is connected adjacent to the tank so that the same conditions are obtained in the chamber as those in the tank.

The float is equipped with a system of permanent magnets to transmit measured values to the local indicator.

The magnet system of the float activates either the magnetic flaps according to the liquid level, or a movable follower magnet in the indicating section of the indicator depending on the method of indication chosen.

The column of reversed yellow magnetic flaps, or the vertical position of the follower magnet, indicates the liquid level.
